Add tests for foreground preservation and refactor geometry node asset

- Implement test to ensure foreground preserves source RGB and Ben2 alpha in WorkerTest.
- Remove outdated tests related to background distance and original background depth.
- Update geometry node asset to reflect new naming conventions and structure.
- Introduce validation for depth plane asset, ensuring correct input/output configurations and attribute handling.
- Adjust confidence and edge parameters in geometry node asset to support a wider range of values.
