- Add Virtual Printer feature - emulate Bambu printer on network

- Virtual printer appears in Bambu Studio/Orca Slicer via SSDP discovery - Secure TLS/MQTT communication with auto-generated certificates - Queue mode (pending uploads) or auto-start mode - Configurable access code for authentication - Docker support with network_mode: host and certificate persistence - Fix backup/restore for virtual printer settings (auto-save no longer overwrites)
