Inspection backlog in Postgres; BullMQ gets a working set

5.4M waiting inspection jobs took 3.3 GB of Redis and most of its single
thread. Producers now add file ids to inspection_queue; index-scheduler
feeds up to INSPECTION_FEED_MAX (50k) into BullMQ. inspection:from-redis
moves the existing backlog over once.
