fix(voice): keep say lines and retry advice in cancelled and failed replies

The cancelled and failed branches ran before the say-line branch, so a
cancelled panel change no longer said "Cockpit exited; the voice panel was
left as you last set it", and AREA_TIMEOUT / OSM_TIMEOUT got "tell the user it
failed" instead of the tool description's "retry once". A cancelled or failed
result with a say line now has it spoken, and those two timeouts are retried
once. Both providers share this instruction.
