Fix: Only use Annotated[Any, ...] fallback for Depends

- Remove unused type: ignore comments that caused mypy lint failure
- Only apply the partial Annotated resolution for Depends metadata
- For other metadata types (File, Form, Query, etc.), return None to
  preserve the original type detection logic
- This fixes the test failures where File/UploadFile params were being
  incorrectly identified as query parameters

     When we have "Annotated[ForwardRef, metadata1, metadata2]" and ForwardRef
     can't be resolved, we still want to preserve the Annotated structure with
     the metadata (like Depends) so that FastAPI can extract dependencies.
+
+    IMPORTANT: This function ONLY returns a value when the metadata is a Depends
+    instance, because replacing the type with Any would break type detection for
+    other parameter types (File, Form, Query, etc.).
