- Save/rollback was done outside of MOC
- Use different contexts for module/provider preferences
- Save providers → also saves modules
- Discard modules → also discards providers
- Use background context because it's not automatically merged (can
rollback)
- Expose ModulePreferences in OpenVPNView as StateObject
- Rework Blacklist to a more reusable ObservableList
- Reapply #988
