PA calibration reads Spoolman first; guard resets a sensor left in PA mode

Browse Source 
- LANE_CALIBRATE_PA: when a calibration will run, assign the lane's spool
  again (SET_SPOOL_ID) so AFC reads the Spoolman temperature now; AFC
  only reads it at spool assignment and Klipper start (TPU calibrated at
  210C after Spoolman was set to 230C). The calibration moved to
  _LANE_CALIBRATE_PA_RUN, rendered after the refresh.
- bdp_guard: an emergency stop during PA_CALIBRATE leaves the sensor in
  PA mode (FIRMWARE_RESTART does not reset it). When arming, read the
  mode register and switch the sensor back to probe mode with a fresh
  baseline before watching it.

# Core: calibrate (or restore from cache) PA for one lane
# ---------------------------------------------------------------------------
# The lane's temperature (and material) come from Spoolman through AFC,
# but AFC only reads them when a spool is assigned or Klipper starts: a
# nozzle temperature changed in Spoolman afterwards was not used (TPU
# calibrated at 210C after Spoolman was set to 230C). When a calibration
# will run, assign the lane's spool again first so AFC reads Spoolman now.
# The calibration is a separate macro, rendered after that refresh.
