Add @trails-cool/jobs package wrapping pg-boss for durable background job
execution using the existing PostgreSQL database. Wire up planner session
expiry as the first scheduled job (hourly, 7-day TTL) — this was previously
dead code that never ran. Add placeholder worker to journal for future
Komoot import and federation jobs.
Infrastructure: grant grafana_reader access to pgboss schema, add job queue
health panels to Service Health dashboard, add failed job alert.

Fix blind spot where Caddy 502 errors were invisible: the dashboards and
alerts queried caddy_http_response_duration_seconds (upstream responses only),
missing 502s that Caddy generates itself. Switch to
caddy_http_request_duration_seconds (server-level, all responses).
Add Journal Grafana dashboard with: 502 rate, response codes, request rate
by route, latency percentiles, container restarts/memory/CPU, Node.js event
loop lag and heap, and Loki log panels for errors and Caddy 5xx entries.
Add color coding to Caddy status code panel (green=2xx, blue=3xx, yellow=4xx,
red=5xx). Add log-based error rate panel to the overview dashboard.
New alerts: container restart loop, PostgreSQL connections > 80, application
crash log detection (Loki), and Caddy 502 rate.

The alert was firing with DatasourceNoData because zero 5xx responses
means the numerator returns empty (not 0). Fixed by:
- Adding `or vector(0)` so zero 5xx returns 0% instead of empty
- Setting `noDataState: OK` as a safety net

The error rate formula (errors/total*100) produces NaN when there's
zero traffic (0/0). Grafana treats NaN as a firing condition.
Use clamp_min on the denominator to return 0% instead.

The threshold expressions were missing the 'expression' field referencing
the query refId, causing 'no variable specified for refId C' errors.

- Create grafana_reader role with SELECT-only access on all schemas
- Init script runs on postgres first boot (docker-entrypoint-initdb.d)
- Grafana PostgreSQL datasource provisioned with read-only credentials
- Enables SQL queries in dashboards (user count, routes, etc.)

Alert rules reference datasourceUid: prometheus/loki which requires
explicit UIDs in the provisioning config.

Grafana provisioning YAML doesn't support env var substitution.
Replace ${ALERT_EMAIL} with hardcoded admin@trails.cool.

Health endpoints:
- /api/health (Journal) and /health (Planner) with DB connectivity check
- Docker healthchecks updated to use app health endpoints
Structured logging:
- Pino with JSON output in production, pretty-print in dev
- Request logging middleware in Planner (method, path, status, duration)
- Replaced console.log/error with structured logger in email and auth flows
Prometheus metrics:
- prom-client with default Node.js metrics + custom histograms/gauges
- /metrics endpoints on both apps
- http_request_duration, planner_active_sessions, brouter_request_duration
Monitoring stack:
- Prometheus, Loki, Grafana containers in docker-compose
- Grafana provisioned with datasources, dashboards, and alert rules
- Caddy access logging (JSON to stdout for Loki)
- grafana.trails.cool with basic auth via Caddy
Dashboards and alerting:
- Overview: request rate, error rate, latency p50/p95/p99
- Planner: active sessions, connected clients, BRouter latency
- Infrastructure: memory, CPU, event loop lag
- Alerts: disk >80%, app down 2min, error rate >5%
