Migrate Event and EventBadge modules to unified type system

- Updated ae_types.ts with ae_Event, ae_EventBadge, and ae_EventBadgeTemplate interfaces.
- Standardized return types (Promise<ae_Event[]>, etc.) for all core loading and CRUD functions in Events module.
- Integrated triple-ID patterns for Dexie and V3 API parity in event-related objects.
- Cleaned up local interface redundancies in favor of unified imports.
