Drop western default apps from the CN default set

Basecamp, Discord, HEY, Google Contacts/Maps/Messages/Photos,
WhatsApp, and X lose their shipped launchers, webapp keybindings,
and the whatsapp-slim extension; aether, libreoffice-fresh, and
obs-studio leave the base package set. The HEY mailto handler and
its registration go with them. Preinstall add/remove lists, the
launcher hide list, and chromium flags stay in sync.
