feat: enhance worktree management and UI integration

- Refactored BoardView and WorktreeSelector components for improved readability and maintainability, including consistent formatting and structure.
- Updated feature handling to ensure correct worktree assignment and reset logic when worktrees are deleted, enhancing user experience.
- Enhanced KanbanCard to display priority badges with improved styling and layout.
- Removed deprecated revert feature logic from the server and client, streamlining the codebase.
- Introduced new tests for feature lifecycle and worktree integration, ensuring robust functionality and error handling.
