package notifications

// Package notifications contains tests for admin notification endpoints.
//
// Test Coverage:
//   - GetNotifications: GET /api/admin/notifications - List unacknowledged notifications
//   - AcknowledgeNotification: POST /api/admin/notifications/{id}/acknowledge - Acknowledge a notification
//
// Features tested:
//   - Pagination (page, per_page)
//   - Filtering by reason
//   - Acknowledging notifications (idempotent, not found cases)
