Enhance Settings.fds management and installation flag handling

- Introduced `comfy_on_disk` and `sync_is_installed` functions to manage the `IsInstalled` flag based on the presence of ComfyUI, ensuring accurate installation state reporting.
- Updated `install_swarm_comfy.py` to clear the `IsInstalled` flag when necessary, allowing the installation process to proceed without conflicts.
- Improved logic to prevent setting `IsInstalled` to true on first boot or empty data volumes, addressing issues with the InstallConfirmWS process.
- Enhanced diagnostics and logging for installation state changes, providing clearer feedback during the installation process.
