Unstuck Me (Early Access feature), fixes and improvements — Backrooms: Extractions Steam update #941200

- Added a feature to unstuck your character when you're stuck with another player (default key is B, customizable in settings). If this happens, please send us a detailed bug report, as this issue is difficult to reproduce. - Adjusted the level initialization system to prevent an issue where several players saw actor spawn points without interaction. Affected elements include extraction targets, almond water dispensers, wooden planks, cutters, roots, and the scene with the table (Paradise). If you encounter problems, please submit a bug report. - Various minor fixes and optimizations. Thank you for helping us continually improve the Early Access experience!
