feat: Implement apt-layer.sh integration in D-Bus methods

- Created ShellIntegration utility for apt-layer.sh command execution
- Implemented async command execution with ThreadPoolExecutor
- Added comprehensive output parsing for install, remove, composefs operations
- Integrated automatic script path discovery with fallback locations
- Added timeout management and error handling for all shell operations
- Extended D-Bus interface with Deploy, Upgrade, Rollback, CreateComposeFSLayer methods
- All methods include proper authorization, transaction management, and error handling
- Updated InstallPackages and RemovePackages to use actual apt-layer.sh commands
- Added proper async/await pattern for non-blocking shell operations

This completes the apt-layer.sh integration phase, enabling the daemon to
orchestrate actual apt-layer.sh commands while providing structured D-Bus
responses with detailed feedback and error handling.
