Fix level system tests for 6-level hierarchy

- Updated getRoleLevel test to include new 'moderator' level at position 3
- Fixed auth.test.ts canAccessLevel tests to match new level assignments:
  - admin: level 4 (was 3)
  - god: level 5 (was 4)
  - supergod: level 6 (was 5)
- Updated API levels route test to expect 6 levels instead of 5
- Fixed capability keyword test to use existing capabilities
- Reduced failing tests from 11 to 4 (96% success rate)
