fix(settings): Sort all settings - incl declarative settings - by priority

Previously declarative settings were sorted by priority but behind the "native" settings,
this is now fixed, meaning a declarative setting with higher priority than an `ISetting` will
be correctly rendered before that `ISetting` in the settings list.
