Transform blackjack from single-round to continuous-play table sessions with
round lifecycle (betting → playing → resolved → betting), split/double down
actions, per-hand bet tracking, leave/join table mid-session, and a responsive
felt-style table UI with arc-positioned player seats.

Adds a full blackjack game with dealer AI, hit/stand/double-down actions,
and per-player payout multipliers (house-edge model). Extends the game
framework with manualStart support and a START_GAME WebSocket message so
hosts can begin when ready. Generalizes bet settlement transaction
descriptions from chess-specific to game-agnostic.
