fix(central): use LAST_PER_SUBJECT and filter non-WF incidents

Browse source 
- consumer.py: change DeliverPolicy from NEW to LAST_PER_SUBJECT to
  get latest state per subject on reconnect instead of replaying backlog
- central_normalizer.py: drop RX and non-wildfire (non-WF) incident
  types early in _parse_wfigs_incidents before they reach the handler
