- Caddy Response Status Codes: caddy_http_responses_total doesn't exist,
use caddy_http_response_duration_seconds_count which has the code label
- pg_stat_statements: enable extension in init script, add custom queries
config for postgres-exporter, remove invalid datname filter from query
- Add postgres/queries.yml to cd-infra SCP sources

The previous PR added Promtail to docker-compose but the CD workflow
didn't copy the config file or include promtail in the service list.

Posts an annotation to Grafana after each successful deploy, tagged
with "deploy" and the service name. Annotations appear as vertical
markers on dashboards, making it easy to correlate deploys with
metric changes.
Uses GRAFANA_SERVICE_TOKEN from SOPS secrets — must be added via
sops infrastructure/secrets.infra.env. Gracefully skips if the
token is not configured.

- 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.)

Remove commit message [restart-all] detection — doesn't work with
GitHub merge commits. Keep only the explicit workflow_dispatch input.

Exporters:
- postgres_exporter: DB connections, transactions, cache hit ratio, query stats
- node_exporter: host CPU, memory, disk, network
- cAdvisor: per-container CPU and memory usage
PostgreSQL:
- Enable pg_stat_statements for query-level performance tracking
- Track index scans vs sequential scans, cache hit ratio
Dashboard (service-health.json):
- DB: connections, size, transactions/s, slow queries, cache hit ratio, index usage
- Host: disk gauge, CPU, memory, network I/O, disk I/O
- BRouter: request latency p50/p95/p99, container CPU + memory
- All containers: CPU and memory comparison

Write decrypted env files to infrastructure/ instead of /tmp/ so
strip_components: 1 correctly places them on the server.

Secrets:
- Add .sops.yaml with age encryption config
- Add encrypted secrets.app.env (app secrets) and secrets.infra.env (Grafana OAuth)
- CD decrypts at deploy time with AGE_SECRET_KEY — all other secrets
move out of GitHub Actions into version-controlled encrypted files
Split CD:
- cd-apps.yml: triggered by apps/packages changes, builds Docker images, deploys apps
- cd-infra.yml: triggered by infrastructure/ changes, copies configs, restarts services
- Remove monolithic cd.yml
Grafana auth:
- GitHub OAuth (trails-cool org), disable login form
- Remove Caddy basic_auth block and all GRAFANA_* env vars/secrets
