WIP: Next set of View.App changes

Updated `SetClipToScreen`, `SetClip`, and `GetClip` methods to accept an `IDriver` parameter, replacing reliance on the global `Application.Driver`. This improves modularity, testability, and reduces implicit global state usage.

- Updated `Driver` property in `View` to use `App?.Driver` as fallback.
- Refactored `DimAuto` to use `App?.Screen.Size` with a default for unit tests.
- Updated all test cases to align with the new method signatures.
- Performed general cleanup for consistency and readability.
