TypeScript WebSocket server for a fair crash game (Aviator-style) with Telegram auth, PostgreSQL persistence, and Redis pub/sub.

• Server-authoritative game loop (betting → flying → crash)
• Telegram Web App initData validation
• Prisma + PostgreSQL for users, bets, sessions, chat
• Configurable crash-point distribution via Redis key crashChances

Client → server: auth, bet, cashout, chat-message

Server → client: auth-success, session-history, balance-update, sync, game-start, game-flying, game-crash

The previous Next.js frontend contained hardcoded ngrok tunnel URLs in TON Connect config — removed during cleanup. Dev auth bypass now requires ALLOW_DEV_AUTH=true.
