fix(config): use stable /dev/ttyF56 symlink for batm3 dispenser

Browse source 
The batm3 dispenser used the raw /dev/ttyUSB0, which is
enumeration-order dependent — a re-plug or reboot could reassign
ttyUSB0 to a different adapter. Switch to the stable udev symlink
/dev/ttyF56 (batm3.nix, serial DDDLb103Y23), matching the validator's
/dev/ttyMEI, so both peripherals bind by identity and survive
re-enumeration (incl. on an internal-SATA flash). Per-box override:
VITE_LAMASSU_DISPENSER_DEVICE.
