feat(grafana): add HAProxy requests dashboard and Richie Postgres datasource
Visualize the ingested HAProxy request logs in Grafana. - add a `richie-postgres` datasource connecting to the Richie DB over the local Unix socket (/run/postgresql; pg_hba trust for user richie) - order grafana after postgresql.service - add the "HAProxy Requests" dashboard: request rate by backend, response -time percentiles (p50-p99), top user-agents/IPs/endpoints, status mix
