feat: implement plan approval functionality in board view

- Introduced PlanApprovalDialog for reviewing and approving feature plans.
- Added state management for pending plan approvals and loading states.
- Enhanced BoardView to handle plan approval actions, including approve and reject functionalities.
- Updated KanbanCard and KanbanBoard components to include buttons for viewing and approving plans.
- Integrated plan approval logic into the auto mode service, allowing for user feedback and plan edits.
- Updated app state to manage default plan approval settings and integrate with existing feature workflows.
