Add warpgate setup wizard, preset command, reconnect command, pre-deploy probe, sync indicator

- warpgate setup: interactive Q&A wizard for first-time configuration
- warpgate preset: apply photographer/video/office presets from PRD §9
- warpgate reconnect: re-probe + re-mount share without full restart
- warpgate deploy: test NAS SFTP connectivity before installing systemd
- warpgate status: show 'All synced — safe to disconnect' indicator
- SupervisorCmd::Reconnect(String) for daemon command channel
