feat: show website favicon and domain in all browser-connected app views

Web app entries (browser:https://...) now display:
- The captured favicon from BrowserIconRegistry (same source as the
  bottom-nav favourite website icon) in ConnectedAppsScreen,
  ConnectedAppDetailScreen, and all three permission/consent dialogs
- The domain name (host) as the title instead of the full URL, via
  OmniboxInput.hostOf() in loadDetailState, NappletConsentSummary,
  buildSignerConsentInfo, and buildConnectInfo
- A globe icon (FavoriteApp.WebApp) instead of the grid icon
  (FavoriteApp.NostrApp) in all consent dialog headers
