Add admin avatars and app logos (#20001)

## Summary
- Add user avatars and workspace logos to the admin general table and
workspace member detail view
- Show app icons in the admin app registrations table and reuse the
shared application display component
- Expose the needed avatar and logo fields through admin GraphQL queries
and backend lookup/statistics services
- Keep workspace fallback behavior consistent when no logo is set and
clean up a few local table styling duplicates

## Testing
- `./node_modules/.bin/tsc -p packages/twenty-front/tsconfig.json
--noEmit --pretty false`
- Manual UI verification of the admin general, workspace detail, and
apps tables
