Add web management UI, offline packages, WinPE consolidation, and docs
- webapp/: Flask web management app with:
- Dashboard showing image types and service status
- USB import page for WinPE deployment content
- Unattend.xml visual editor (driver paths, specialize commands,
OOBE settings, first logon commands, raw XML view)
- API endpoints for services and image management
- SETUP.md: Complete setup documentation for streamlined process
- build-usb.sh: Now copies webapp and optional WinPE images to USB
- playbook: Added webapp deployment (systemd service, Apache reverse
proxy), offline package verification, WinPE auto-import from USB
