// PURPOSE:
// Get all unread notifications for specified user ID
//
// RULES:
// 1. Uses COL_NOTIFICATIONS collection
// 2. Filters by to_user_id and read=false status
// 3. Expands author and to_user_id relations
// 4. Sorts by created date (newest first)
// 5. Returns Promise<Notification[]>
// 6. Disables caching for real-time results
