Add gPodder sync API and bump SW cache to v5
- Implement gPodder API v2 compatible endpoints at /api/2/:
  - Auth: login/logout via HTTP Basic Auth or session
  - Devices: list and register sync devices
  - Subscriptions: get/add/remove per device, delta sync with ?since=
  - Episode actions: upload play/position events, syncs to EpisodeProgress
- Server URL for AntennaPod: https://diora.creamfresh.xyz/api/2/
- Bump SW cache diora-v4 → v5 to force re-fetch of updated app.js
