fix: odstranění matoucích chybových hlášek z dialogu Správa obchodů

Wolt hlásí stav podniku, ne rozvozu — status zůstane na "ready" i celou dobu,
co kurýr objednávku veze. Vyzvednutí proto poznáme podle pickup_eta: dokud je
v budoucnosti, jídlo ještě čeká v podniku, po vyzvednutí se ustálí na skutečném
čase. Dřív se stav odvozoval jen z příznaků kurýra, takže objednávka zůstala
viset na kroku "Vyzvedávání", i když už byla na cestě.

Kurýr má nově tři odvozené stavy: assigned (ještě nevyzvedl), delivering (veze
ji k nám) a delivering_other (veze ji, ale nejdřív doručuje cizí objednávku —
Wolt objednávky spojuje a kurýr se pak na mapě vzdaluje). Oba stavy delivering*
znamenají krok "Na cestě", tooltip u nich vysvětlí objížďku.

+# 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
+
+## Changelog (user-facing "What's new")
+
+When you add or change a user-visible feature, you MUST also record it in `server/changelogs/` so users see it via the in-app changelog (served by `server/src/routes/changelogRoutes.ts`, sorted newest-first with a `?since=` filter).
+
+Steps:
+
+1. Create or open the file for today's date: `server/changelogs/YYYY-MM-DD.json` (use today's date; one file per day).
+2. The file content is a **JSON array of Czech strings**, one short user-facing sentence per change. Example:
+   ```json
+   [
+     "Proklik na nabídku podniku ze stránky objednávek",
+     "Možnost přidat URL pro sledování stavu doručení pro Bolt Food"
+   ]
+   ```
+3. If a file for today already exists, append your entry to its array instead of creating a new file.
+4. Write entries in Czech, phrased for end users (describe the benefit, not the implementation). Skip purely internal/refactor changes that users won't notice.
+5. The route caches files in memory at read time, so a server restart is needed to pick up new/changed changelogs in a running dev instance.
