- Implemented separate sound effects volume control in settings. - Updated backend to handle new `sfx_volume` parameter. - Enhanced UI to include sound effects volume slider in admin panel. - Integrated sound effects for various user interactions (clicks, navigation, alerts). - Added a new global sound engine to manage audio synthesis without external files. - Updated documentation for Docker deployment and Windows packaging. - Refactored audio context management to ensure sound effects are available post user interaction.
