fix: oprava updateData v Redis storage (node-redis v5 nemá executeIsolated)

- Socket.io Redis adapter pro sdílený stav přes repliky
- graceful shutdown serveru
- WATCH/MULTI v updateData pro race-condition-safe aktualizace
- lease mechanismus pro push reminder (zabrání duplicitnímu odesílání)
- k8s/ manifesty pro testovací kind cluster
- Dockerfile: opraven EXPOSE port na 3001
- .gitignore: ignorovány Claude pracovní soubory

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Luncher is a lunch management app for teams — daily restaurant menus, food ordering, pizza day events, and payment QR codes. Czech-language UI. Full-stack TypeScript monorepo.
+
+## Monorepo Structure
+
+```
+types/    → Shared OpenAPI-generated TypeScript types (source of truth: types/api.yml)
+server/   → Express 5 backend (Node.js 22, ts-node)
+client/   → React 19 frontend (Vite 7, React Bootstrap)
+e2e/      → Playwright E2E tests (separate package)
+```
+
+Each of the four directories has its own `package.json`. Package manager: **Yarn Classic**.
+
+Deployment files at repo root: `Dockerfile` (multi-stage, dva runner targety: výchozí `runner` pro lokální build, `runner-prebuilt` pro CI s předem sestavenými artefakty), `compose.yml`, `compose-traefik.yml`.
+
+## Development Commands
+
+### Initial setup
+```bash
+cd types && yarn install && yarn openapi-ts   # Generate API types first
+cd ../server && yarn install
+cd ../client && yarn install
+cd ../e2e && yarn install
+```
+
+### Running dev environment
+```bash
+# All-in-one (tmux):
+./run_dev.sh
+
+# Or manually in separate terminals:
+cd server && NODE_ENV=development yarn startReload   # Port 3001, nodemon watch
+cd client && yarn start                               # Port 3000, proxies /api → 3001
+```
+
+### Building
+```bash
+cd types && yarn openapi-ts      # Regenerate types from api.yml
+cd server && yarn build          # tsc → server/dist
+cd client && yarn build          # tsc --noEmit + vite build → client/dist
+```
+
+### Tests
+```bash
+# Server unit tests (Jest)
+cd server && yarn test                  # All tests in server/src/tests/
+cd server && yarn test dates            # Run one file by name
+cd server && yarn test -t "name"        # Run by test name pattern
+
+# E2E (Playwright) — requires prebuilt server
+cd server && yarn build
+cd e2e && yarn test                     # chromium + firefox, baseURL 127.0.0.1:3001
+cd e2e && yarn test:ui                  # interactive UI mode
+cd e2e && yarn report                   # open last HTML report
+```
+
+Jest setup (`server/src/tests/setupEnv.ts`) forces `STORAGE=memory`, deletes `MOCK_DATA`, and sets a fixed `JWT_SECRET`. Playwright auto-starts the prebuilt server and authenticates via the `remote-user: e2e-user` trusted-header path; locally uses `STORAGE=json` + `MOCK_DATA=true`, CI uses `STORAGE=redis`.
+
+### CI pipeline
+Gitea Actions — `.gitea/workflows/ci.yaml` (no `.github/` equivalent):
+
+1. `generate-types` — runs `yarn openapi-ts`, uploads artifact
+2. `server-test` — Jest
+3. `server-build` + `client-build` — parallel tsc/vite builds
+4. `e2e` — Playwright in `mcr.microsoft.com/playwright:v1.59.1-jammy` with a Redis service container; only Firefox installed in CI
+5. `docker-build` — master branch only, uses `Dockerfile` with `--target runner-prebuilt` (skládá image z artefaktů `server-build` + `client-build`)
+6. `notify` — Discord + ntfy webhooks
+
+### Formatting
+Prettier is installed in `client/` (devDependency only, no script or config) — invoke via `yarn prettier <path>` with defaults.
+
+## Architecture
+
+### API Types (types/)
+- OpenAPI 3.0 spec in `types/api.yml` — all API endpoints and DTOs defined here
+- `api.yml` is a thin aggregator — actual endpoint specs live in `types/paths/<domain>/*.yml`, shared schemas in `types/schemas/_index.yml`
+- `yarn openapi-ts` generates `types/gen/` (client.gen.ts, sdk.gen.ts, types.gen.ts)
+- Both server and client import from these generated types
+- **When changing API contracts: update api.yml first, then regenerate**
+
+### Server (server/src/)
+- **Entry:** `index.ts` — Express app + Socket.io setup
+- **Routes:** `routes/` — 9 modular Express route handlers (food, pizzaDay, voting, notifications, qr, stats, easterEgg, dev, changelog)
+- **Services:** domain logic files at root level (`service.ts`, `pizza.ts`, `restaurants.ts`, `chefie.ts`, `voting.ts`, `stats.ts`, `qr.ts`, `notifikace.ts`)
+- **Helpers:** `mock.ts` (fake menu data for `MOCK_DATA=true`), `pushReminder.ts` (push notification reminders), `utils.ts` (shared utilities)
+- **Auth:** `auth.ts` — JWT + optional trusted-header authentication
+- **Storage:** `storage/index.ts` factory selects implementation; backends: `json.ts` (file-based, dev), `redis.ts` (production), `memory.ts` (tests). Data keyed by date (YYYY-MM-DD).
+- **Restaurant scrapers:** Cheerio-based HTML parsing for daily menus from multiple restaurants
+- **Pizza Chefie integration:** `chefie.ts` scrapes pizzachefie.cz for Pizza day menus and salads (only active when a Pizza day is open)
+- **WebSocket:** `websocket.ts` — Socket.io for real-time client updates
+- **Mock mode:** `MOCK_DATA=true` env var returns fake menus (useful for weekend/holiday dev)
+- **Config:** `.env.development` / `.env.production` (see `.env.template` for all options)
+
+### Client (client/src/)
+- **Entry:** `index.tsx` → `App.tsx` → `AppRoutes.tsx`; `Login.tsx` is the auth screen; `FallingLeaves.tsx` is a seasonal visual effect
+- **Pages:** `pages/` (StatsPage)
+- **Components:** `components/` (Header, Footer, Loader, PizzaOrderList, PizzaOrderRow, and modals in `components/modals/`)
+- **Context providers:** `context/` — `auth.tsx`, `settings.tsx`, `socket.js`, `eggs.tsx` (note: `socket.js` is the only non-TSX context file)
+- **Hooks:** `hooks/` (`usePushReminder.ts`)
+- **Utils:** `utils/` (`parsePrice.ts`)
+- **Styling:** Bootstrap 5 + React Bootstrap + custom SCSS files (co-located with components)
+- **API calls:** use OpenAPI-generated SDK from `types/gen/`
+- **Routing:** React Router DOM v7
+
+### Data Flow
+1. Client calls API via generated SDK → Express routes
+2. Server scrapes restaurant websites or returns cached data
+3. Storage: Redis (production) or JSON file (development)
+4. Socket.io broadcasts changes to all connected clients
+
+## Environment
+
+- **Server env files:** `server/.env.development`, `server/.env.production` (see `server/.env.template`)
+- Key vars: `JWT_SECRET`, `STORAGE` (json/redis/memory), `MOCK_DATA`, `REDIS_HOST`, `REDIS_PORT`
+- **Docker:** multi-stage Dockerfile, `compose.yml` for app + Redis. Timezone: Europe/Prague.
+
+## Conventions
+
+- Czech naming for domain variables and UI strings; English for infrastructure code
+- TypeScript strict mode in both client and server
+- Server module resolution: Node16; Client: ESNext/bundler
+- `TODO.md` tracks open bugs and roadmap items — worth scanning before starting non-trivial work

 - Zkopírovat `server/.env.template` do `server/.env.development` a upravit dle potřeby
-- Spustit `./run_dev.sh`. Na jiných platformách se lze inspirovat jeho obsahem, postup by měl být víceméně stejný.

+- [ ] `foodRoutes.ts` per-pod rate limiter (`rateLimits` map) — s více replikami může uživatel překročit limit ~N× rychleji; přesunout do Redis (např. `INCR` + `EXPIRE`)
+- [ ] `easterEggRoutes.ts` — náhodně generované URL easter eggů jsou per-pod; URL funguje pouze na podu, který ji vygeneroval; zvážit deterministické seedy nebo sdílení přes Redis
+- [ ] `service.ts` — komplexní víceúrovňové funkce (`addChoice`, `removeChoiceIfPresent`) provádějí více po sobě jdoucích zápisů do stejného Redis klíče; pro plnou atomicitu je potřeba per-klíčový distribuovaný zámek (Redlock nebo `SET NX EX`) nebo sloučení logiky do jednoho `updateData` volání
 - [ ] HTTP_REMOTE_TRUSTED_IPS se nikde nevalidují, hlavičky jsou přijímány odkudkoli
 - [ ] V případě zapnutí přihlašování přes trusted headers nefunguje standardní přihlášení (nevrátí žádnou odpověď)
   - [ ] Nemělo by se jít dostat na přihlašovací formulář (měla by tam být nanejvýš hláška nebo přesměrování)

+# Kubernetes — Luncher HA
+
+Manifesty pro nasazení Luncheru na Kubernetes s vysokou dostupností (3 repliky, Redis adapter pro Socket.io, WATCH/MULTI atomické zápisy, graceful shutdown).
+
+## Prerekvizity
+
+- kubectl nakonfigurovaný na cílový cluster
+- `helm` nainstalovaný
+- Redis Stack image přístupný z clusteru (`redis/redis-stack-server:7.2.0-v14`)
+- Obraz `luncher:ha-test` načtený do clusteru (viz níže)
+
+## Lokální kind cluster (testik) — setup
+
+### 1. Smazat a znovu vytvořit cluster s port mappings
+
+```powershell
+$env:KIND_EXPERIMENTAL_PROVIDER = "nerdctl"
+# Přidat nerdctl do PATH (Rancher Desktop)
+$env:PATH += ";$env:LOCALAPPDATA\Programs\Rancher Desktop\resources\resources\win32\bin"
+
+kind delete cluster --name testik
+kind create cluster --name testik --config k8s/kind/testik.yaml
+```
+
+### 2. Sestavit a načíst obraz
+
+```powershell
+docker build -t luncher:ha-test .
+
+# Uložit a načíst přes nerdctl (kind + nerdctl provider)
+nerdctl save luncher:ha-test -o luncher.tar
+kind load image-archive luncher.tar --name testik
+Remove-Item luncher.tar
+```
+
+### 3. Nainstalovat Traefik (rke2-traefik)
+
+> **Prerekvizita (Rancher Desktop):** Pokud Rancher Desktop běží s `kubernetes.options.traefik=true`,
+> host-switch.exe obsadí port 80 dříve než kind. Vypni traefik v k3s:
+> ```powershell
+> rdctl set --kubernetes.options.traefik=false
+> ```
+>
+> **Prerekvizita — inotify limity:** Čtyř-uzlový kind cluster vyčerpá výchozí
+> `fs.inotify.max_user_instances=128`. kube-proxy pak padá s „too many open files".
+> Zvyš limit v rancher-desktop WSL2 (přežije restart WSL2, ale ne reboot — přidej do
+> `/etc/sysctl.d/99-kind.conf` pro trvalost):
+> ```powershell
+> wsl -d rancher-desktop -- sysctl -w fs.inotify.max_user_instances=1280
+> ```
+
+```powershell
+# rke2-traefik je v rke2-charts, ne rancher-charts
+helm repo add rke2-charts https://rke2-charts.rancher.io
+helm repo update
+
+# Nejdřív CRD chart, pak samotný chart
+helm install traefik-crd rke2-charts/rke2-traefik-crd -n kube-system --create-namespace
+helm install traefik rke2-charts/rke2-traefik -n kube-system `
+  --set "tolerations[0].key=node-role.kubernetes.io/control-plane" `
+  --set "tolerations[0].operator=Exists" `
+  --set "tolerations[0].effect=NoSchedule"
+```
+
+Ověř že Traefik DaemonSet běží na control-plane (má hostPort 80):
+```powershell
+kubectl get ds -n kube-system traefik-rke2-traefik
+kubectl get pods -n kube-system -o wide | Select-String traefik
+```
+
+### 4. Nainstalovat Reloader
+
+[stakater/Reloader](https://github.com/stakater/Reloader) sleduje změny Secret a ConfigMap a automaticky spustí rolling restart Deploymentu — odpadá nutnost ručního `kubectl rollout restart` po rotaci `JWT_SECRET` nebo `ADMIN_PASSWORD`.
+
+Manifest je vendorovaný ve verzi v1.4.16 (`k8s/base/reloader.yaml`). Nasadit do `default` namespace:
+
+```powershell
+kubectl apply -f k8s/base/reloader.yaml
+kubectl rollout status deploy/reloader-reloader
+```
+
+Reloader běží cluster-wide díky `ClusterRoleBinding` — nepotřebuje žádnou konfiguraci per-namespace. Deployment Luncheru má anotaci `reloader.stakater.com/auto: "true"`, která říká Reloaderu, ať sleduje všechny Secrety a ConfigMapy odkazované přes `envFrom`.
+
+### 5. Nasadit Luncher
+
+```powershell
+# Namespace + Redis
+kubectl apply -f k8s/base/namespace.yaml
+kubectl apply -f k8s/base/redis-statefulset.yaml
+kubectl apply -f k8s/base/redis-service.yaml
+
+# Počkat na Redis
+kubectl rollout status statefulset/redis -n luncher
+
+# Server secret (nebo použít šablonu server-secret.yaml)
+kubectl create secret generic luncher-secrets -n luncher `
+  --from-literal=JWT_SECRET=dev-secret-change-me `
+  --from-literal=ADMIN_PASSWORD=admin
+
+# Server
+kubectl apply -f k8s/base/server-configmap.yaml
+kubectl apply -f k8s/base/server-deployment.yaml
+kubectl apply -f k8s/base/server-service.yaml
+kubectl apply -f k8s/base/server-pdb.yaml
+kubectl apply -f k8s/base/ingressroute.yaml
+
+# Počkat na server
+kubectl rollout status deploy/luncher -n luncher
+```
+
+## Testovací scénáře
+
+### Baseline
+
+```powershell
+kubectl get pods -n luncher -o wide
+# Ověř: 3 pody na 3 různých worker uzlech, status Running
+```
+
+### Rolling update bez výpadku
+
+V jednom terminálu posílej provoz:
+```powershell
+# Nainstaluj hey: go install github.com/rakyll/hey@latest
+hey -z 60s -c 20 http://luncher.localhost/api/health
+```
+
+Ve druhém terminálu spusť rollout:
+```powershell
+kubectl rollout restart deploy/luncher -n luncher
+```
+
+**Kritérium: 0 non-2xx odpovědí, 0 connection errors.**
+
+### Node drain
+
+```powershell
+kubectl cordon testik-worker2
+kubectl drain testik-worker2 --ignore-daemonsets --delete-emptydir-data
+# PDB zabrání souběžnému drainu druhého nodu
+kubectl get pods -n luncher -o wide  # pody se přeplánují
+kubectl uncordon testik-worker2
+```
+
+### Ověření Socket.io cross-pod
+
+1. Otevři dvě záložky prohlížeče na `http://luncher.localhost`
+2. Z jednoho podu vyvolej změnu:
+   ```powershell
+   kubectl exec -it deploy/luncher -n luncher -- curl -s -X POST localhost:3001/api/...
+   ```
+3. Ověř, že druhá záložka (pravděpodobně jiný pod) obdrží WebSocket event
+
+### Concurrent write test
+
+1. Otevři stejnou Pizza day objednávku ve dvou záložkách
+2. Simuluj souběžné odeslání (otevřít DevTools → síť → odeslat obě požadavky současně)
+3. Ověř Redis: `kubectl exec -it redis-0 -n luncher -- redis-cli JSON.GET luncher:<datum>`
+   — oba zápisy musí být zachovány (WATCH/MULTI retry)
+
+### Auto-rollout při změně Secret / ConfigMap
+
+Reloader automaticky spustí rolling restart, kdykoli se změní `luncher-secrets` nebo `luncher-config`:
+
+```powershell
+# Příklad: rotace admin hesla
+kubectl -n luncher patch secret luncher-secrets --type=merge `
+  -p '{"stringData":{"ADMIN_PASSWORD":"nove-heslo"}}'
+
+# Reloader detekuje změnu resourceVersion a patchne pod template
+kubectl rollout status deploy/luncher -n luncher
+
+# Ověř anotaci přidanou Reloaderem na pod template
+kubectl get deploy luncher -n luncher -o yaml | Select-String "STAKATER"
+```
+
+**Kritérium: pody se automaticky vyrolují bez ručního restartu. PDB zajistí, že alespoň jeden pod zůstane dostupný.**
+
+## Pořadí aplikace manifestů
+
+1. `reloader.yaml` (do `default` namespace — musí být před Deployment)
+2. `namespace.yaml`
+3. `redis-statefulset.yaml` + `redis-service.yaml`
+4. `server-configmap.yaml` + `server-secret.yaml`
+5. `server-deployment.yaml` + `server-service.yaml` + `server-pdb.yaml`
