Refactor and enhance DA3 and BEN2 debug panels, introduce mesh export functionality

- Renamed DA3 and BEN2 debug panels for clarity and consistency.
- Added a new function to draw DA3 input settings to reduce code duplication.
- Implemented mesh export functionality, including confidence thresholding and edge filtering.
- Updated export format options to include new mesh type and adjusted related properties.
- Enhanced job handling to move generated inputs into job root and manage temporary directories.
- Improved error handling and file management during export processes.
- Added unit tests for new mesh functionality and ensured existing tests cover changes.
