Rebuild UI on the Noo design system

Replaces the Material 3 screens with the Noo design system: warm neutrals, one violet accent, pill controls, Schibsted Grotesk/ Instrument Sans, Lucide icons, no gradients/shadows. - New lib/widgets/noo/ component kit (core, lists, files, media, nav, overlays) plus lib/theme/design_tokens.dart for the color/type/space/ radius/motion tokens. - Rebuilt the app shell (top/bottom bars, drawer, desktop sidebar and toolbar), every tab (Files/Offline, Photos, Favorites, Recent, Activity, Trash, Shares), Settings, the lock and login screens, the media viewer, search, the details/share sheets, and the share-upload and move/copy destination pickers. - Added a design canvas (linked from DESIGN_SYSTEM.md) covering the screens the spec didn't already describe, with matching Android and iOS chrome; wrote up the approved recipes into DESIGN_SYSTEM.md §4. - Removed now-dead legacy widgets (media_grid_tile, swipeable_item, sync_status_badge, selectable_thumbnail) and updated architecture.md/styling.md/standards.md to describe the new structure and component/testing conventions. - Added widget tests for the noo/ component kit. This is a UI-only rework: no provider/model/service behavior changed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
