Restore Event Session search stability and advance platform-wide string ID standardization

- Restored Event Session search by standardizing on 'event_id' for Dexie queries and implementing dual-layer filtering (local + API guard) to prevent broad results from clobbering filtered views.
- Advanced String-Only ID Standardization (Phase 2) by updating generic object processors across all event library modules to support both base IDs and legacy '_random' variants.
- Refactored Event Presenter and Presentation components to support standardized '_id_li' props while maintaining backward compatibility.
- Standardized common helper identifiers to snake_case (e.g., 'prevent_default') in the Events module.
- Verified Staff and Poster email notification logic in the Bulletin Board module.
- Updated .gitignore and cleaned up test artifacts.
