Use 'nb' locale code for Norwegian

Switch Norwegian locale code from "no" to the ISO 639-1 code "nb" for consistency. Updated Android locale_config.xml, renamed resource folder values-no to values-nb (strings moved/renamed accordingly), and changed the AppLanguage enum to use "nb". Also removed a now-duplicate media_series string entry in the renamed resources.
