feat: resolved URI display and drill-down for TO/TO_DYNAMIC nodes

- Show resolved endpoint URI as teal italic line on diagram nodes
  when execution overlay is active
- Enable drill-down for TO and TO_DYNAMIC nodes (not just DIRECT/SEDA)
- Use runtime resolvedEndpointUri from execution overlay for drill-down
  when static endpointUri doesn't match
- Increase node height from 50px to 56px to accommodate the third line
