Feature/streamline settings (#1614)

* Cleanup graphql setting mutation

* Validate values read from config

* Generate server-reference.conf files from ServerConfig

* Remove unnecessary enum value handling in config value update

Commit df0078b725 introduced the usage of config4k, which handles enums automatically. Thus, this handling is outdated and not needed anymore

* Generate gql SettingsType from ServerConfig

* Extract settings backup logic

* Generate settings backup files

* Move "group" arg to second position

To make it easier to detect and have it at the same position consistently for all settings.

* Remove setting generation from compilation

* Extract setting generation code into new module

* Extract pure setting generation code into new module

* Remove generated settings files from src tree

* Force each setting to set a default value
