Implement live syncback feature and enhance API for service data transfer

- Added a new `performSyncback` function in the `App` module to handle the synchronization of service data from the game to the server.
- Introduced a `SyncbackConfirm` UI component to confirm syncback actions from the user.
- Updated the API to include a new `/api/syncback` endpoint for handling syncback requests, validating protocol and server versions.
- Enhanced the `SyncbackSignal` mechanism to facilitate communication between the server and the syncback process.
- Added tests to ensure the functionality of the live syncback feature and its integration with the CLI.

These changes improve the overall synchronization capabilities of the application, allowing for real-time updates and better project management.
