feat: implement follow-up and commit features for waiting_approval status

- Added functionality to allow users to send follow-up prompts for features in the waiting_approval status, enabling continued work with additional instructions.
- Implemented a commit feature that allows users to mark waiting_approval features as verified and commit changes directly.
- Updated the UI to include buttons for follow-up and commit actions on Kanban cards and integrated dialogs for user interaction.
- Enhanced the feature loader and executor to handle the new status and actions appropriately.

This update improves the workflow for managing features that require manual review and enhances user experience in the auto mode.
