Adds full PWA compliance: web app manifest, service worker with
cache-first static / network-first scoreboard strategy, and a
generated hockey puck icon (512, 192, 180, 32px) on the app's
dark navy background. Includes all required meta tags for iOS
standalone mode and a /favicon.ico route.

- utc_to_eastern: use zoneinfo instead of hardcoded EDT offset (-4)
so start times are correct in both EST and EDT
- standings: fetch before truncate so a failed API call doesn't wipe
existing standings data
- routes: call parse_games() once per request instead of three times
- scheduler: wrap run_pending() in try/except so an unhandled exception
doesn't kill the background thread
