Add FastAPI Integration Tests

[MuddyHope]

Description

We need to implement robust integration tests for using @TrackQuery inside FastAPI routes. This will ensure the tracking and logging system behaves correctly in real-world API scenarios. Additional development and potential rework of decorators or logging middleware might be necessary to ensure clean and consistent behavior.

Acceptance Criteria:

• Create a minimal FastAPI app with example routes using @TrackQuery.

• Test both synchronous and asynchronous route handlers.

• Use fastapi.testclient.TestClient for testing.

• Validate logs using caplog or mock logger where needed.

• Ensure that logging occurs correctly and doesn't interfere with route execution.

• Handle slow execution (sleep), exceptions, and edge cases.

If needed, refactor the decorator to better support ASGI/FastAPI lifecycle.

🛠️ Notes:

May require changes to decorator or logger setup to support ASGI and middleware contexts.

Could explore an optional FastAPI middleware instead of (or in addition to) decorators for broader coverage.
