Buy, bid, and know the price

Buying happens in Discord: /market browse shows the same listings with a Buy button, and a ⚖️ Bid button on the ones taking bids. Selling is /market list (add bid: to take bids for a day).

Auctions moved onto the market: a listing can take ⚖️ bids. Bid with the ⚖️ Bid button on /market browse (⏳ Closing lists the lots ending within the hour); take bids on your own card with /market list and bid:.

A card's own page shows its full price history. In Discord: /market trend.
