Subject: openhop/repeater: fixes from first real deploy on ubuntu

- create spi/gpio groups and udev device rules (Raspberry Pi OS ships them, Ubuntu does not)
- hardware CS via spidev (cs_pin -1); a manual cs_pin on a kernel-owned CE line fails EBUSY
- align RAK6421 pin maps with upstream's hardware catalog: en_pins for the FEM enables,
  gpiod backend on chip 0 (catalog says chip 1, wrong for Pi 4)
- us RF preset is now MeshCore USA/Canada (Recommended): 910.525 / SF7 / BW62.5 / CR5
- set storage.storage_dir; omit mqtt_brokers entirely (any key enables the MQTT pusher)
- fetch radio-settings/radio-presets json into the data dir (pip omits them and the web
  setup wizard's hardware step is empty without them)
- config deployed 0660 with a vaultable repeater.security block so the daemon can persist
  credentials and re-templates no longer wipe them
- sudoers rule so the web UI can restart the service after config changes
