- The `routes_hash` setting will be used during the boot process to update the hash
of currently loaded routes.yaml file in case it's different from last restart
no-issue
They will be used to store webhook information so that we can persist it between
boots and simplify the creation process of webhooks in members

- We made changes to settings table structure in 3.22 which added new columns for `group` and `flags`
- Any new setting needs explicit group and flag migrations since or they fallback to default group value of `core`
- This tests ensures
- hash is updated in DB integrity test anytime default-settings are changed
- that a migration is present by maintaining a whitelist of allowed core settings and failing if new setting is added without correct group migration
