fix: resolve 6 Gitea issues (#9, #10, #12, #14, #15, #21)

- #21: Add missing await in removeChoiceIfPresent() to prevent user appearing in two restaurants
- #15: Add 1-hour TTL for menu refetching to avoid scraping on every page load
- #9: Block stats API and UI navigation for future dates
- #14: Add restaurant warnings (missing soup/prices, stale data) with warning icon
- #12: Pre-fill restaurant/departure dropdowns from existing choices on page refresh
- #10: Add voting statistics endpoint and table on stats page
