- Ensure settings had only one method but would benefit from class+DI pattern before extracting it into an outside module.
- The logic is now also less coupled with "routes" and single source/destination paths. It's all configureable instead and might be reused if similar pattern is needed for example with redirect settings defaults.
- The main goal here is getting this settings related code out of the routing service as it really doesn't belong there
- This settings file is used purely by the API to get and set files - its not really anything to do with actual routing
- This file calls out to the bridge to do a reload, which helps decouple slightly
- More refactoring is needed to get rid of the urlService dependency
- Note this file is really similar to the redirects one, it would be good to merge them
