Subject: [PATCH 1/5] feat: add comprehensive unit tests for core services

- Added unit tests for IdentityService with full CRUD coverage
- Added unit tests for VerificationService including approve/reject flows
- Added unit tests for AuthService covering authentication logic
- All tests include proper mocking of dependencies
- Tests cover both happy paths and error cases (NotFoundException)
- Achieves high code coverage for critical business logic

Subject: [PATCH 3/5] fix: resolve clippy error in identity_registry

- Changed tuple key from &(&owner, &document_hash) to (owner.clone(), document_hash.clone())
- Soroban storage requires owned values in tuple keys, not references
- Fixes E0277 trait bound error for TryFromVal
- All clippy checks now pass
