Add notifications: morning/evening briefings + breaking alerts

- Settings hub (gear → SettingsView) hosting Notifications and Connectivity
  (Connectivity previously had no entry point).
- NotificationsView: permission flow, breaking/new-story alerts with a
  min-signal threshold, morning & evening briefings with time pickers, and a
  weather toggle + location, plus a "send test briefing" action.
- NotificationManager: schedules daily briefings, builds "Jarvis" content
  (weather + top signal stories), fires breaking alerts off WebSocket
  story.created events, and refreshes via a BGAppRefresh task.
- WeatherService: Open-Meteo geocoding + daily forecast (no API key/entitlement).
- AppDelegate registers the background-refresh handler at launch; Info.plist
  gains UIBackgroundModes + BGTaskSchedulerPermittedIdentifiers.
