/**
 * Test script for notification delivery and reminder check.
 *
 * Usage (inside Docker container):
 *   npx tsx scripts/test-notifications.ts
 *
 * Or from host:
 *   docker compose exec app npx tsx scripts/test-notifications.ts
 *
 * What it does:
 *   1. Lists all configured notification channels
 *   2. Sends a test notification through each enabled channel
 *   3. Runs the reminder check logic once with verbose logging
