feat: add troubleshooting side panel and advanced queue controls

- Implemented a global toggle to enable/disable background queue processing.
- Added a Side Panel (Sidebar.html) to view pending edits.
- Added per-item controls: 'Delete' to remove from queue, 'Push' to force update.
- Updated 'onEditQueue.ts' with robust error handling for batch processing.
- Updated documentation (README, ARCHITECTURE) to reflect new features.
- Fixed 'clasp' deployment issues by cleaning up manifest management.
