refactor(types): add native parameter and return types to UserSettings

All six public/protected methods now carry PHP 8.x native types instead
of relying on docblocks alone.  Two test mocks that used willReturnMap
were migrated to willReturnCallback so they return a typed default
(false / []) instead of null when no entry matches.
