fix(idaa): stabilize Recovery Meetings search and broaden visibility logic

- Resolved 400 Bad Request by whitelisting 'physical', 'virtual', and 'external_person_id' fields in backend searchable_fields.
- Broadened server-side search by removing restrictive AND filters for location types, moving the inclusive OR logic to the client-side filter layer.
- Hardened handle_search_refresh error handling to clear results on category filter changes (Type, Physical, Virtual) while maintaining flicker protection strictly for text search typing.
- Restored permissive visibility for Trusted users, allowing them to see hidden/disabled items regardless of Edit Mode.
- Optimized plural object loading in Archives and Events modules using concurrent Promise.all.
- Standardized ID handling across the search flow to prevent Dexie lookup failures.
- Finalized well-commented code across IDAA modules to document search strategies and workarounds.
