Fix empty Caddy and pg_stat_statements panels in service-health dashboard
- 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
