malkhut: ExchangeProfile gains available_order_types per venue

Each exchange now declares which normalized order types it supports:
- binance: limit, market, stop_market, stop_limit, post_only, ioc, fok, trailing_stop, reduce_only
- bingx: limit, market, stop_market, stop_limit, post_only, ioc, fok, trailing_stop, reduce_only
- bybit: limit, market, stop_market, stop_limit, post_only, ioc, fok, trailing_stop, reduce_only

Backward compatible: new field has default=('limit', 'market').
Enables: agents/adversaries check is_type_available() before placing orders.
