test: increase test coverage for listings, auth, and search modules

Add 33 new test files to reach coverage targets:
- Listings: 13 → 28 test files (50%+)
- Auth: 21 → 36 test files (50%+)
- Search: 10 → 13 test files (59%+)

New tests cover domain entities, value objects, services, guards,
decorators, DTOs, repositories, controllers, and event handlers.
Total: 204 test files, 1178 tests passing.
