feat(manacore): implement mukke, presi, and context dashboard widgets

Add the 3 missing widget components that were registered but not implemented:

- MukkeLibraryWidget: shows library stats (songs, playlists, favorites),
  recent songs with artist/duration
- PresiDecksWidget: shows recent presentations with public/private
  indicator, descriptions, and update dates
- ContextDocsWidget: shows recent documents grouped by type (text,
  context, prompt) with space names, falls back to space list

All widgets follow the established pattern: APP_URLS for links,
WidgetSkeleton/WidgetError for loading/error, auto-retry on failure.
