#1145: macOS app menu follows the interface language

About FilmCraft and Join the ArtCraft Discord… in the macOS app menu take
the translated labels of the same Help menu commands and are updated on
a language switch. Hide, Hide Others and Quit get their text from the
catalogs instead of muda's English defaults and keep their native
actions. menus::NATIVE_APP_MENU lists these native-only labels together
with the Settings submenu, so the app and the tests use the same keys.

German rows for the three new keys; "Quit FilmCraft" is already
translated in es, ja, zh-cn and fr (the app.quit shortcut), the other
languages show English until they have translations. The German menu
test accepts and requires the native app menu labels.

Closes #1145
