Switch to chips-only play: real cards at the table, winners picked on screen

- Remove the deck, hole cards, board, hand evaluator and reveal logic
  (cards are dealt physically; the site only tracks bets, pots and stacks)
- Showdown now waits for a winner per pot (main/side), chosen by a player
  still in the hand or the host; multiple winners split the pot
- All-in with no further betting goes straight to showdown
- Remove the 30s action clock / auto sit-out (everyone is at the same table)
- UI: winner picker panel (main winner auto-fills side pots), compact table
