fix(ams): confirm drying start instead of trusting the firmware ack (#2533)

The Start Drying button gave no feedback at all and reported success on the
strength of the MQTT ack alone. On a P1S the firmware answers
ams_filament_drying with result=success and then silently declines, and
P1-family firmware never publishes dry_sf_reason — so the #971 reason guard
is inert there and the card just sat unchanged.

Both drying mutations now toast. The start toast claims only that the command
was sent, since that is all the ack proves; the amber countdown badge remains
the signal that a cycle is genuinely live. After a start, the card watches the
unit's dry_status/dry_time (straight from the info bitmask, updated on every
push); firmware reaches DryStatus 1 within seconds of a real start, so still
sitting at zero 30s later means the cycle never began. Bambuddy now says so
and names the two causes: AMS power adapter not connected, or the printer not
idle. Unlike the dry_sf_reason guard this is model-agnostic.
