Enhance logging for syncback operations and patch applications

- Added detailed logging for syncback operations, including additions, removals, and updates, to improve traceability and debugging.
- Implemented summary logs for patch applications in both the client and server, capturing the number of changes made.
- Enhanced logging in the ChangeBatcher and ApiService to provide insights into property changes and instance updates during syncback processes.
- Improved error handling and logging for VFS events to ensure better visibility of file operations.
