Summary

• Restore delegated click handling for Carbon dropdown triggers and options across the configuration flow.
• Populate the country / territory selector from an ISO-3166 fallback list.
• Load state / province and city options dynamically, with manual-entry fallbacks when the location service has no data or is unavailable.
• Wire selection state back into the existing delivery validation and draft flow.
• Remove the dangling loadMakes() call at the end of the configure page script; vehicle make loading is owned by the vehicle fitment component.

Validation

• Source inspection confirms the delivery controls now have trigger and option handlers, and the destination control references are initialized.
• CI/build validation pending.
