build(apple): flag raw string literals in SwiftUI initializers

The typed-resource rules missed a bare string literal passed as the leading arg of
a view initializer (e.g. Label("send_stop_sharing", …)), which is an implicit
LocalizedStringKey. Add a rule covering Text/Label/Button/Section/Picker/etc.
(empty labels allowed). Fixes the two dynamic-content Text sites it surfaced by
switching them to Text(verbatim:).
