Remove metadata storage and handling from watch history

Removes the metadata argument from `WatchHistoryService.publishView` and cleans up the associated caching and resolution logic in `watchHistory.js` and `watchHistoryFeed.js`. Deletes `js/watchHistoryMetadata.js` as it is no longer used.

This simplification ensures watch history strictly manages pointers and timestamps, leaving metadata resolution to higher-level consumers. It also reduces the payload size and complexity of persisted history records.

Tests have been updated to reflect the API changes.
