refactor(events, idaa): standardize on String-only IDs and remove '_random' suffix

Aligned the Events Badges, Templates, and IDAA Bulletin Board modules with
Aether UI/UX v3 standards by prioritizing semantic String IDs (e.g., event_id,
badge_id) over legacy '_random' variants in API helpers, Dexie processors,
and UI components.

- Refactored badge and template loaders to use clean ID field names.
- Updated search and LiveQuery logic in badge management views.
- Cleaned up unused imports and legacy code in +layout and +page components.
- Standardized ID mapping in generic object processors.
- Improved IDAA post creation UX with autofocus and empty title defaults.
