fix(edit-wo): build dashboard URL eagerly, outside action closure

The action ->url() closure was resolving \$this to the Action instance
and its ->getRecord() returned null in header-action context, so the URL
came out as /app/work-orders//dashboard.

getHeaderActions() runs after mount(), so \$this->record is guaranteed
populated. Compute the URL string once and pass it as a plain value.
