feat(events): reorganize badge admin tools and enhance dependency tracking

- Migrated 'Add New Badge' and 'Upload Badge List' to centralized Event Settings hub.
- Secured Admin Tools visibility with Administrator access and Edit Mode requirements.
- Restored and modernized Badge Template management route with Svelte 5 runes.
- Patched 'Archive' and 'Session' database interfaces to resolve compiler errors.
- Added project-wide dependency comments to key interfaces (Archive, Badge, Session) to prevent cascading change regressions.
- Fixed duplicate import errors in the Settings page.
