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).
