mqtt_relay reads state.left_aux_fan_speed, but the SimpleNamespace fixture in
test_plate_clear_mqtt_notification enumerates its fields explicitly, so the two
status-payload tests raised AttributeError. I updated the equivalent fixture in
test_printer_manager_status_broadcast and missed this one — running only the
touched suites is what hid it.
Also addresses the round-2 review notes:
- exhaust_fan_present: documented that the H2 series reports part 3 too, so the
flag is not model-specific despite the name.
- Mask the part id after shifting, matching get_flag_bits(id, 4, 8), for
consistency with the state decode. No behaviour change for any observed id.
- Noted the unmapped H2 id 6 beside the id branches.
- Reject fan=aux2 when the printer reports no left_aux_fan_speed, so a POST
against an A1 no longer sends M106 P10 for absent hardware. The UI already
hid the badge; this closes the same hole on the API.
- Added a test asserting EXHAUST_FAN_LABEL_MODELS and the frontend's
MODELS_WITH_EXHAUST_LABEL cannot drift apart.
