✨ Allow `Response` type hint as dependency annotation

## Summary
Fixes #10127

Using `Response` as a type hint with `Depends` would fail with an assertion error:
```python
def endpoint(response: Annotated[Response, Depends(modify_response)]):
    # AssertionError: Cannot specify \`Depends\` for type Response
```

## Changes
Modified the type annotation handling in `analyze_param()` to check for `Depends` before applying special type handling. When a `Depends` is specified, the dependency is called normally and its return value used.

## Usage
Now supports:
- `response: Annotated[Response, Depends(modify_response)]`
- `response: Response = Depends(modify_response)`

While still supporting regular injection:
- `response: Response`

## Testing
Added comprehensive tests in `tests/test_response_dependency.py`
