v1.2.2

Fixes

• The firmware flasher now lists devices in a predictable order. Devices
  used to appear in whatever order they were discovered; they're now sorted
  alphabetically by name, so the same device is always in the same place.
• Calibration controls stay inside their box on narrow layouts. On narrow
  screens — and when the editor column tightens on desktop — the uncalibrated
  field-of-view diagram and the "Calibrate room size" button could spill
  outside their card. Both now scale and wrap to fit.
