feat: update instance profile to use admin user instead of initialized flag

- Changed InstanceProfile to include admin user field
- Updated GetInstanceProfile method to retrieve admin user
- Modified related tests to reflect changes in admin user retrieval
- Removed owner cache logic and tests, introducing new admin cache tests
