Subject: [PATCH 1/3] style: fix Annotated pattern in audit_logs.py to resolve
 Ruff B008 and maintain compatibility

Refactor `app/api/audit_logs.py` to use the `Annotated` type hint pattern while maintaining default values for dependencies using module-level singletons.

- Resolves B008: Function-call in default argument.
- Maintains compatibility with decorators (e.g., `@require_login`) that call the function without explicitly providing the `db` argument.
- Uses standard FastAPI patterns for query parameters with constant defaults.
- No changes to API runtime behavior.

Subject: [PATCH 3/3] fix(api): use proper Annotated pattern in audit_logs.py,
 remove experimental root test files

- Remove _db_dep singleton and its use as default value in function signatures
- Use DbSession = Annotated[Session, Depends(get_db)] directly (matches files.py pattern)
- Declare db: DbSession without a default (FastAPI DI provides the session)
- Delete 10 experimental test_*.py files left at repo root from B008 debugging
