Refactor watch history to use plaintext monthly buckets

Browse Source 
- Update `js/nostrEventSchemas.js` to remove encryption tagging and update schema for `WATCH_HISTORY`.
- Update `js/nostr/watchHistory.js` to:
  - Bump storage version to 4.
  - Bucket items by `YYYY-MM`.
  - Publish plaintext JSON payloads with only event IDs and timestamps.
  - Remove encryption logic from publishing.
  - Update fetching to handle plaintext and fallback to legacy parsing.
- Update `js/watchHistoryService.js` to strip metadata from queued items and handle new snapshot response.
- Update `tests/watch-history.test.mjs` to reflect new plaintext behavior and disabled obsolete tests.
