perf(events): refactor load functions to be non-blocking

Browse Source 
- Eliminated blocking 'await' calls in '+page.ts' for main Events, Session, Location, and Presenter views.
- Implemented Stale-While-Revalidate (SWR) pattern: pages now render instantly using cached IndexedDB data while API refreshes run in the background.
- Removed expensive sequential loops in load functions, allowing the reactive UI (via LiveQuery) to handle data arrival as background tasks complete.
