Second opener follows the same editor

This should be the same capture experience as the first opener editor. The difference is only the item label, the existing values shown to the user, and the saved result returning to the workspace as Opener 2.

What changes

• Header, summary, and return state all refer to Opener 2.
• Copied values from Opener 1 can be edited before save.
• The saved line item remains separate from Opener 1 even if most values match.
