feat: add inpaint region functionality and related tools

- Enhanced cursor behavior for new tools: semantic select, mask lasso, and mask rectangle.
- Updated mask edit state to include mask asset ID and kind.
- Implemented inpaint region commands for adding, applying, and removing inpaint regions.
- Introduced new operations for lasso and semantic selection tools.
- Created UI components for candidate review and inpaint region management.
- Added tests for inpaint region commands to ensure functionality.
- Updated various components to support new inpaint features and improve user experience.
