Add `QuickSettingsDialog` and enhance UI interactions

- Introduced `QuickSettingsDialog` as a pop-up for quick access to settings and actions.
- Added pointer-based handling in `HoverBar`, including right-click for quick settings.
- Updated `DraggableProgressBar` with exposed `UpdateThumbPosition` method and layout refinements.
- Improved theme by introducing chevron icons and updating `NavigationDialog` for better clarity.
- Refined `HoverBar` layout by increasing max width and adding tooltips to buttons.
