Rebuild Noo as a full Nextcloud client: auth, media, and Material You UI

Replaces the starter template with Login Flow v2 auth, WebDAV-backed
Files/Photos/Activity tabs, a swipeable media viewer with PDF/text/video
preview, Material You dynamic theming, a frosted-glass floating nav bar,
and a rebranded app icon/identity (com.example -> family.nasa).
