feat: implement bulk feature verification and enhance selection mode

- Added functionality for bulk verifying features in the BoardView, allowing users to mark multiple features as verified at once.
- Introduced a selection target mechanism to differentiate between 'backlog' and 'waiting_approval' features during selection mode.
- Updated the KanbanCard and SelectionActionBar components to support the new selection target logic, improving user experience for bulk actions.
- Enhanced the UI to provide appropriate actions based on the current selection target, including verification options for waiting approval features.
