Add comprehensive notification system (Agent 8)
Implement multi-channel notification system with: - Core notification service with email, push, and in-app channels - Email templates for all notification types (welcome, plant registered, transport alerts, farm alerts, harvest ready, demand matches, weekly digest) - Push notification support with VAPID authentication - In-app notification management with read/unread tracking - Notification scheduler for recurring and scheduled notifications - API endpoints for notifications CRUD, preferences, and subscriptions - UI components (NotificationBell, NotificationList, NotificationItem, PreferencesForm) - Full notifications page with preferences management - Service worker for push notification handling
