"""One-shot setup for the live Pi probe.

Does three things:
  1. Rotates fusion_plating_iot.ingest_token to a real random secret.
  2. Picks (or creates) a test tank + temperature parameter.
  3. Creates the fp.tank.sensor record mapped to the real probe serial
     (28-000000b276e4), with plating-realistic alert thresholds.

Run:
    cat fp_iot_setup_live_sensor.py | odoo shell -c /etc/odoo/odoo.conf -d admin --no-http

Prints the new token at the end — copy it into the Pi poller script.
