nan 8aac4822c6 feat: Implement background depth distance feature for depth processing
- Added `background_depth_distance` property to `ActiveJob` and `RunJob` classes to manage background depth settings.
- Updated job execution to handle background depth distance, allowing for fixed negative displacement in depth calculations.
- Introduced new functions in the worker module to apply background depth distance to depth frames and manage original background depth.
- Enhanced tests to cover new functionality, ensuring correct behavior of background depth processing and reference depth extraction.
- Refactored job submission to run in a separate thread, improving responsiveness during execution.
