jozamudi a8426b5922 server-persisted watch history with position + resume
- POST/GET /api/history: JSON file in data/history.json (50 entries
  kept, top 5 shown on home), upsert per (anime, episode)
- watch position saved every ~10s of playback + on pause/unload
- resume: opening an anime seeks to the saved position unless
  >=95% through (then starts fresh); position shown on home items
- drops localStorage; server is the source of truth (verified:
  fresh watch -> new session resumes at saved pos -> home lists it)

"""app.py — ani-web: FastAPI over upstream.py + HLS proxy + static UI.
Browser playback: hls.anidb.app sends no CORS headers, so the player is
pointed at /stream/{token}; the proxy fetches upstream (with the same
Cloudflare workaround) and rewrites playlist URIs to go through itself.
