feat(tv): home row adjustmnets

[mattsigal]

Changes Included:

1. Performance & Query Optimization

• Progressive Asynchronous Loading: Refactored fetchAllData to decouple the initial layout rendering (Guide, My Media, and Continue Watching) from slower, third-party/external API rows (IMDb, TMDb, Seerr, and recommendations). The main loading spinner is dismissed instantly once initial local rows render.
• Staggered Loader Scheduler: Implemented a staggered loader manager using setTimeout at 300ms intervals. This spaces out the initial load of secondary rows (genres, collections, playlists, recos, IMDb) instead of firing 40+ concurrent database requests at the exact same millisecond. This resolves SQLite database locks, server CPU spikes, and request timeouts.
• Merged CW & Next Up Fetch Protection: Added a .catch(() => null) fallback to the merge-items query to ensure that in-flight request aborts or timeouts do not reject the main dashboard promise group and crash page initialization.
• Safeguarded cache spreads: Checked cachedRowData truthiness to prevent fatal TypeError: cachedRowData is not iterable crashes when browser storage caches are empty or reset.

2. Layout, Row Ordering, and Syncing Fixes

• Server/TV Key Bidirectional Mapping: Standardized key mapping in rowOrderMap and enabledRowIdsSet to check both TV-style hyphenated IDs (e.g. latest-media, recently-released) and server-style unhyphenated IDs (e.g. latestmedia, recentlyreleased). This resolves issues where "Recently Added" and "Recently Released" rows disappeared or were assigned bad sorting weights during boot.
• Automatic Settings Synchronization: Added a useEffect hook to trigger settings synchronization from the server immediately upon user authentication to automatically enable the Moonbase sync plugin on reload/recompile.
• Prevented Re-render Loops: Added a deep validation check to syncFromServer's settings setter to return the unchanged state reference if no properties changed, eliminating React context consumer re-render loops.

3. Media Card & Asset Fixes

• Genre Representative Pipe Delimiter: Corrected unmatched genre item search requests by joining genre names with the pipe character (|) instead of a comma (,). Commas caused Jellyfin to look for a non-existent genre named literally Action,Comedy,Drama, returning empty results and preventing sample images from loading.
• Letterboxd Ratings Display: Corrected the truthiness validation of showUserRatings inside externalHomeRows.js to show star reviews by default when undefined.
• External Row Backdrop Focus: Resolved focus issues where backdrop URLs failed to load for external list items (IMDb, Letterboxd, Seerr).

THINGS NOT WORKING:

1. Recently Added rows are not being pulled in
2. Row requests need optimization, they are opening too many connections and thrashing the server.
3. The My Media items are not expanding as a "Modern" row
4. The Genres tiles aren't using the custom logic to use a sample item's backdrop/poster instead of Jellyfin's thumbnail.
5. The IMDb/TMDb rows aren't pulling in backdrops for the focused view.
