fix(devices): read devices and device options through to the database

The device cache was filled once at construction, so a token minted by one
replica was unknown to every other replica already running and a token revoked
on one replica stayed valid on the others until they restarted.

- drop the eager device and device options dictionaries
- read devices and device options from the database on every query
- push the device query filters and ordering into SQL
- open the request's database context only for the api key fallback
- cover both directions against real PostgreSQL with two manager instances
