feat: add fake trading module with crypto, stocks, forex and gold
Paper trading system with 5 commands (trade_topup, trade_buy, trade_sell, trade_convert, trade_stats). Supports VN stocks via TCBS, crypto via CoinGecko, forex via ER-API, and gold via PAX Gold proxy. Per-user portfolio stored in KV with 60s price caching. 54 new tests.
