feat: enhance worktree functionality and UI integration

- Updated KanbanCard to conditionally display status badges based on feature attributes, improving visual feedback.
- Enhanced WorktreeSelector to conditionally render based on the worktree feature toggle, ensuring a cleaner UI when worktrees are disabled.
- Modified AddFeatureDialog and EditFeatureDialog to include branch selection only when worktrees are enabled, streamlining the feature creation process.
- Refactored useBoardActions and useBoardDragDrop hooks to create worktrees only when the feature is enabled, optimizing performance.
- Introduced comprehensive integration tests for worktree operations, ensuring robust functionality and error handling across various scenarios.
