Enables stage-2: the prod dashboard_api request pool connects as the READ-ONLY
dashboard_ro role (DATABASE_URL) while the v_trips refresher keeps a privileged
connection via REFRESH_DATABASE_URL (falls back to DATABASE_URL when unset, so
single-role/staging deploys are unchanged). Avoids the FIX-D02 trap (a read-only
role cannot REFRESH).
Adds deploy_dashboard_api.sh (the prod bridge deploy, now version-controlled):
strips inherited DATABASE_URL, sets REFRESH_DATABASE_URL=<app role> +
DATABASE_URL=dashboard_ro, CORS incl. fleetops.rahamafresh.com.
