Adds the backend half of the ExpressDispatchAgent flow. Express orders can now be created batch by batch (bulk create only accumulates them, unassigned), then an operator hits one endpoint to hand the whole pending set to the agent for tenant-scoped assignment + road sequencing. The normal B2C flow is untouched. - POST /admin/expressbooking/dispatch: manual trigger. Console-auth, tenant- scoped; gathers the tenant's pending unassigned express orders (or a chosen subset) and publishes express.dispatch_requested. - internal API for the agent: GET /internal/express/riders (tenant's available riders), GET /internal/express/bookings, POST /internal/express/assign (writes the agent's decided assignments with their sequence; re-checks the already- assigned guard so the agent can't double-assign). - booking_assignment_service.go: extracted a behavior-preserving assignMilerTx core; AssignMilerToBooking is unchanged in behavior. assignExpressStops writes a batch, one FCM per rider instead of one per stop. - EXPRESS JetStream stream / express.dispatch_requested subject. - Gated behind EXPRESS_AGENT_ENABLED (default off): deploying this changes nothing until the agent is confirmed running and the flag is flipped.
