feat(dlob): pin markets and wire mevnode endpoints

- Limit DLOB workers/ingestors to SOL-PERP, DOGE-PERP, JUP-PERP across base and staging config.
- Set publisher market ids to [0,7,24] for drift protocol.
- Add overlay patches for dlob-publisher and dlob-server to use wg0 RPC endpoints 10.66.66.1:8899/8900 in staging and prod.
- Extend Agave dashboard and add PrometheusRules for RPC up/lag/I/O alerts.
- Ensure overlays reference new patches for automated ArgoCD rollouts.
