Refactor watch history to use single monthly event

Browse Source 
Replaces the legacy chunked storage architecture with a single encrypted event per month.
- Renames `buildWatchHistoryChunkEvent` to `buildWatchHistoryEvent`.
- Updates `WatchHistoryManager` to publish and fetch single events, maintaining read compatibility for legacy chunks.
- Simplifies payload construction and removes chunk indexing logic.
- Updates tests to verify single-event publishing and legacy fallback.
