refactor(config): name configuration delivery parts consistently

Call the whole component configuration delivery and name its parts after
what they do. The synchronous Scheduler becomes DeliveryQueue (queue.rs)
and the task that drains it becomes the delivery worker.
SupervisorConfigRouter becomes SupervisorConfigTransport, because "route"
also named cross-replica work. That work, its peer messages
(PeerNotifyConfigUpdateRequest/Response, matching the RPC), and its metrics
now say peer notification instead of hint. Lane::Direct becomes
Lane::Sandbox to match the sandbox-scoped wording used elsewhere.

Metric changes:
- openshell_supervisor_config_dispatch_wait_seconds is now
  openshell_supervisor_config_queue_wait_seconds
- openshell_supervisor_config_peer_hints_total is now
  openshell_supervisor_config_peer_notifications_total
- openshell_supervisor_config_pending lane labels direct and route are now
  sandbox and peer_notify
