Summary: Let organizers automatically add time to an auction when a bid is placed close to its scheduled end.

What: Add an optional setting that extends the auction end time by a configurable amount when a bid is received within a set number of minutes before the auction closes.

Why: This would give other bidders a fair chance to respond to last-second bids and encourage competitive bidding.

Customer context: An auction organizer asked whether the auction could automatically extend when a bid is received close to the end time.
