no issue
- moved `config` and `site` API output generation to a `public-config` service allowing all API versions to use `publicConfig.config` or `publicConfig.site` in their query methods
- updated `config` and `site` API output serializers to use an allow-list that limits the data returned for each API version
* moved `server/config` to `shared/config`
* updated config import paths in server to use shared
* updated config import paths in frontend to use shared
* updated config import paths in test to use shared
* updated config import paths in root to use shared
* trigger regression tests
* of course the rebase broke tests
