feat: Use postgres as a queue

We've been keen to try this for a while as it means we can remove redis as a
dependency, which makes Immich easier to setup and run.

This replaces bullmq with a bespoke postgres queue. Jobs in the queue are
processed either immediately via triggers and notifications, or eventually if a
notification is missed.
