refactor: Rename CompactToolbar to Toolset and Enhance Toolbar Functionality

- Renamed CompactToolbar class to Toolset for improved clarity and consistency in naming.
- Introduced WidgetMeasurement for tracking widget dimensions, enabling debugging and test automation.
- Updated toolbar methods to include measurement functionality, logging overflow warnings, and improved layout handling.
- Removed the deprecated SettingsBar and Toolset classes to streamline the codebase.
- Adjusted CMake configuration to reflect the new file structure and included widget measurement source files.
