9409706c58 feat(monitoring): add comprehensive alerting rules, Alertmanager, and DR validation 
Expand production monitoring with full alert coverage for database connections,
Redis memory/connections, container resources, disk usage, service health, and
backup integrity. Add Alertmanager service with Slack routing for critical and
warning alerts, and add automated backup verification to the pg-backup cron
schedule. Update runbook with DR validation procedures and quarterly checklist.

- Expand Prometheus alert rules from 4 to 24 alerts across 7 groups
- Add Alertmanager container (prom/alertmanager:v0.27.0) with Slack routing
- Configure inhibition rules (critical suppresses warning for same service)
- Schedule automated backup verification at 04:00 UTC daily
- Add Alertmanager datasource to Grafana provisioning
- Update runbook with Section 9: DR Validation (automated + manual procedures)
- Add SLACK_WEBHOOK_URL and Grafana vars to .env.example

90839cf542 feat(monitoring): add API latency Grafana dashboard and alerting rules 
Create comprehensive Grafana dashboard for API latency monitoring with:
- p50/p95/p99 stat panels and time series for all endpoints
- Per-endpoint latency breakdown with route/method template variables
- Top 10 slowest endpoints table and bar chart (by p99)
- Request rate (by method) and error rate (4xx/5xx) panels
- Error rate percentage (5xx/total) with SLO threshold
- Latency heatmap and histogram distribution panels

Add Prometheus alerting rules:
- ApiLatencyP99High: p99 > 1s for 5m (warning)
- ApiEndpointLatencyP99High: per-endpoint p99 > 2s (warning)
- ApiLatencyP99Critical: p99 > 3s for 3m (critical/SLO breach)
- ApiErrorRate5xxHigh: 5xx rate > 1% for 5m (warning)

Fix api-overview.json using wrong metric name
(http_request_duration_seconds → goodgo_api_request_duration_seconds).
