Currently, the discovery of "extraConfigs" in the GUI only happens when navigating from "optional" to "config". Since some services do not have optional dependencies, they will skip the "optional" page.

This leads to an issue where services that require extra configuration do not allow the user to specify that configuration unless they have optional dependencies, which can be problematic for standalone services that require such configuration like MySQL.

One example of where this is handled properly is with the volume requirements. Following this pattern, one viable solution would be to abstract all "config discovery" into a helper function, similar to the discoverVolumeRequirements function.
