Add Moonraker Update Manager integration

🎉 One-click updates from Mainsail/Fluidd UI!

New files:
- moonraker/update_manager.cfg - Moonraker config
- moonraker/README.md - Setup instructions
- install.sh - Auto-install/update script
- README.md - Complete project documentation

Features:
✅ Update Manager entry in Mainsail/Fluidd
✅ One-click updates from web UI
✅ Automatic Klipper restart after update
✅ Safe install (doesn't overwrite custom user_settings.cfg)
✅ Installs calibration macros automatically
✅ Professional update workflow

Setup:
1. Add [include open4neptune-new/moonraker/update_manager.cfg] to moonraker.conf
2. Restart Moonraker
3. Machine → Update Manager → open4neptune-configs → Update

Like official Klipper plugins! 🔥
