feat: enhance sidebar functionality for mobile and compact views

- Introduced a floating toggle button for mobile to show/hide the sidebar when collapsed.
- Updated sidebar behavior to completely hide on mobile when the new mobileSidebarHidden state is true.
- Added logic to conditionally render sidebar components based on screen size using the new useIsCompact hook.
- Enhanced SidebarHeader to include close and expand buttons for mobile views.
- Refactored CollapseToggleButton to hide in compact mode.
- Implemented HeaderActionsPanel for mobile actions in various views, improving accessibility and usability on smaller screens.

These changes improve the user experience on mobile devices by providing better navigation options and visibility controls.
