feat(02-03): create alertService with deduplication and email
- evaluateAndAlert() iterates ProbeResults and skips healthy probes - Maps 'down' -> 'service_down', 'degraded' -> 'service_degraded' - Deduplication via AlertEventModel.findRecentByService with configurable cooldown - Creates alert_events row before sending email (suppression skips both) - Recipient read from process.env.EMAIL_WEEKLY_RECIPIENT (never hardcoded) - createTransporter() called inside function scope (Firebase Secret timing fix) - Email failures caught and logged, never re-thrown
