Add a button to copy a hand's situation as an AI prompt

Reviews and replays get a "copy for AI" button that builds a text
describing the hand (stacks, positions, actions, pots, board, revealed
cards, result and the site's own judgments) plus questions, ready to
paste into an AI chat. Hidden opponent cards are left out so the
evaluation is based only on what Hero could see.
