I archived a lot of cards, because I want to keep track of those cards even though they are marked as done. Up to the point where some lists became empty. So I deleted the list, forgetting that some archived cards actually belong to them. And it deleted those cards.

Describe the solution you'd like

I'd like a way to archive lists, keeping the hierarchy (ie the link with the cards that belonged to them in the past)

Describe alternatives you've considered

• a list trashbin, or a card trashbin
• at least a warning stating "All the cards in this list, including archived ones, will be deleted, do you want to delete anyway
• or any combination of the above ("do you want to archive the list instead?", "Do you want to delete the list and keep the archived cards?", ...)

Additional context
Add any other context or screenshots about the feature request here.

The issue names no files, tests, or entry points. Start by locating list deletion and archived-card handling in the Deck code, then determine the intended behavior for lists containing archived cards. Done means the selected archive, warning, or retention behavior is implemented and verified for that case.
