The station-control code rebuilt a fresh driver on every status poll and every relay set. Stateful boards (Denkovi FTDI D2XX, USB-serial) hold an OS handle only one opener can own, so the first poll opened the board and leaked the handle, and every poll after failed with 'device in use' — the relays greyed out a second after Save and auto-control never switched. Drivers are now cached per device and reused, closed on config change. Adds a Test-connection button + detect feedback in the device editor (reported by VK4MA).
