Melitta Barista & Nivona: reconstructing coffee-machine BLE control

Melitta Barista & Nivona for Home Assistant implements Bluetooth LE control of supported coffee machines through their shared Eugster/Frismag protocol. Its reference maps GATT characteristics, the HU handshake, encrypted frames, and status and brew commands. The integration exposes machine state and settings; Melitta models also have recipe and maintenance controls. Nivona support is in alpha.
