Enhance watch history hydration with relay hints and verbose logging

The watch history hydration process was sometimes failing to retrieve video metadata, resulting in "Untitled video" cards. This was primarily due to only querying the generic relay list and potentially missing content hosted on specific relays.

This commit improves the robustness of `createWatchHistoryHydrationStage` in `js/feedEngine/watchHistoryFeed.js` by:
1.  Collecting unique relay hints from the pointer objects (`item.pointer.relay`) of items needing hydration.
2.  Merging these hints with the user's `readRelays` (or fallback `relays`) list. This ensures that if a specific video is known to exist on a niche relay, that relay is queried during the metadata fetch.
3.  Replacing conditional debug logging with `devLogger.info` and `devLogger.warn` to provide detailed insights into the hydration process (item counts, selected relays, generated filters, and fetch results), aiding in future diagnosis.

These changes ensure the application attempts to fetch metadata from all relevant sources indicated by the history data itself.
