feat(archy): extend useArchy with wallet/files context, add ArchyAppsGrid component

- Add wallet (Lightning balance, channels) and files (Nextcloud) context
  categories to useArchy composable with AI prompt injection
- Create archy-apps.ts data file mapping all 18 Archy services
- Build ArchyAppsGrid component with live status from bridge
- Wire ArchyAppsGrid into ContentPanel when embedded in Archy
