Implement branch selection and worktree management features

- Added a new BranchAutocomplete component for selecting branches in feature dialogs.
- Enhanced BoardView to fetch and display branch suggestions.
- Updated CreateWorktreeDialog and EditFeatureDialog to include branch selection.
- Modified worktree management to ensure proper handling of branch-specific worktrees.
- Refactored related components and hooks to support the new branch management functionality.
- Removed unused revert and merge handlers from Kanban components for cleaner code.
