FastAPI endpoint find usages

[cdeil]

Could you please add "find usages" to endpoints - probably as an inlay hint or gutter symbol?

The existing "go to route" is like a "go to definition" and it's very good, very nice. :-)

This would be the complement to go the other way.

For us it would allow me to see and go to any test for a given endpoint where we call the endpoint from TestClient and would make navigating the codebase silky smooth.
