feat(offline): implement Dexie fallbacks and fix type stability in Events module

- Offline Resilience: Added local Dexie fallbacks to load_ae_obj_id__* and load_ae_obj_li__* functions for Events, Sessions, Locations, Exhibits, and Badges.
- Type Safety: Standardized ae_Event and ae_EventSession interfaces in ae_types.ts; resolved Promise assignment errors in load functions (+page.ts).
- Bug Fixes: Corrected duplication in ae_events__event_location.ts and ae_events__event_badge_template.ts; fixed missing try_cache parameters.
- UI Stability: Fixed Dexie LiveQuery subscription pattern in bulk print view and ensured proper property access in layout load functions.
