Refactor and enhance UI components

- Updated `CableInfoWidget` to include a TODO comment regarding manufacturer verification.
- Refactored `CustomTab` and `CustomTabWidget` to remove notification label functionality, simplifying the class structure.
- Improved `DeviceInfoWidget` by adding a destructor to manage graphics view memory and initializing graphics scene properly.
- Introduced `DiskUsageBar` and `DiskUsageWidget` classes to manage disk usage visualization, including hover popover functionality for detailed information.
- Enhanced `MediaPreviewDialog` to include more descriptive window titles and adjusted status label styling based on platform.
- Added platform-specific functionality in `macos.h` and `macos.mm` for popover management.
- Cleaned up `ToolboxWidget` by adjusting label styles and removing fixed sizes for better responsiveness.
