fix(portal): cancel quickstart when copilot key selection is cancelled

When the account has multiple Copilot keys and the user cancels the key-selection
prompt, abort the quickstart (ActionResult.cancelled) instead of silently
finishing without Copilot/AI integration. No-key and single-key paths are
unchanged (skip silently / auto-use).
