Linked Listing Back Link

Listings should include a backlink to the linked listing. This would allow them to navigate back and forth to the "main listing" more easily, while also displaying the "main listing" somewhere on the "linked listing" page.

My suggestion is to include a toggle button for each linked listing option in the widget, allowing sponsors to choose whether a backlink should be displayed for a specific listing. This way, backlinks can be added selectively.

The toggle could offer two display options:

1. A plain-text link (similar to the "offered by" section on the Deal detail page).

2. Displaying the main linked listing in the sidebar.
