Add tests for authentication and security features

- Implement unit tests for password handling in `auth_test.ts`, covering bcrypt and legacy password hashes.
- Create a fake database for user management to facilitate testing of the `AdminHandler`.
- Validate JWT-based identity verification against database records.
- Introduce tests for credential encryption and registry management in `security_test.ts`.
- Ensure registry passwords are securely stored and can be decrypted correctly, including legacy support.
- Add utility functions for password hashing and verification in `auth.ts`.
