fix(strategy): add missing order_type/sub_order_type, condition_orders, and group_tag

- Add --order-type and --sub-order-type as required flags to order strategy create
  (server requires both; omitting them caused every create call to 400)
- Remove --side from strategy create (field no longer exists in the API)
- Make --open-price optional in strategy create (matches API spec)
- Fix --gas-price in strategy create to convert gwei→wei (consistent with swap)
- Add --condition-orders and --sell-ratio-type to swap command for
  take-profit/stop-loss conditions attached after a successful swap
- Add --group-tag (LimitOrder/STMix) to order strategy list
- Add --order-type to order strategy cancel
- Add StrategyConditionOrder interface; extend SwapParams with condition_orders
  and sell_ratio_type; add order_type/sub_order_type to StrategyCreateParams;
  remove side; add order_type to StrategyCancelParams
- Update docs/cli-usage.md: fix strategy create table, add chain fee requirement
  notes (SOL requires priority_fee+tip_fee; BSC requires gas_price), add
  condition_orders example and strategy_order_id response field, add
  TRADING_BOT_UNAVAILABLE error code
