Fix dashboard: always use hybrid (no HNSW dependency), 15s timeout, error display

Browse Source 
The search hung because pure AI mode calls HNSW which is RAM-only —
gone after every lakehouse restart. Now ALL AI/hybrid searches go
through the /search endpoint which uses brute-force when HNSW isn't
loaded. Added 15s AbortController timeout so fetch never hangs.
Added window.onerror handler to show JS errors on page.
