feat(drying): enable AMS drying for H2C at firmware 01.02.00.00+ (issue #1624)

  H2C was in _DRYING_UNSUPPORTED_MODELS. Move to _DRYING_MIN_FIRMWARE
  with the same 01.02.00.00 floor as H2S / P2S. Both SSDP model codes
  the H2C advertises (O1C single-nozzle, O1C2 dual-nozzle) get the
  same gate so supports_drying() fires correctly regardless of which
  form is stored on the printer record.
