Refine loop detector dependency injection

[matdev83]

Summary

• allow BackendRequestManager to accept an injected loop-detector factory before falling back to the global service locator
• wire the DI container registrations so scoped providers create detectors via the factory instead of constructing them manually
• add unit coverage that verifies factory injection both directly and through a scoped ServiceCollection

Testing

• python -m pytest (fails: environment lacks optional snapshot/bandit tooling and dependencies)

Import Callable for backend request manager DI tests

The new tests annotate factories with Callable (e.g., _make_manager_with_factory) but the module only imports Any and cast. Importing this test file raises NameError: name 'Callable' is not defined, causing the suite to fail before exercising the new behaviour. Add Callable to the typing imports so pytest can run.
