Changes

This makes sure we return info from the boefjes.json and schema.json instead of returning data in the database. This solves issues where we updated these files locally but did not see the changes reflected due to a stale database.

Closes #3850

Demo

QA notes

Please enable dns-records and then delete the schema.json file in the kat_dns directory in the boefjes module. In the KATalogus, we should see no more settings for dns-records (perhaps after a restart of the boefjes container: docker compose restart boefje katalogus).
