Subject: Expire messages after 90 days.

This is intended to manage storage growth. A community with broadly steady traffic will now reach a steady state (ish) where the amount of storage in use stays within a steady band.

The 90 day threshold is a spitball; this should be made configurable for the community's needs.

I've also hoisted expiry out into the `app` classes, to reduce the amount of non-database work repo types are doing. This should make it easier to make expiry configurable later on.

Includes incidental cleanup and style changes.
