feat(订阅): 新增 crypto-strategy 信号格式化器

Motivation: crypto-strategy 交易信号采用 envelope 外壳与字符串化/嵌套的 payload，原有 trade_signal 格式化器无法解析，需要独立的转换逻辑以生成通知文本和事件数据。 Changes: * 新增 crypto_strategy 消息转换器，解析 envelope 及嵌套、字符串化、扁平三种 payload 形态 * 根据平仓/止盈/卖出等标志推断交易动作，生成对应事件类型与中文通知文本 * 提取订单号、策略代码、价格、杠杆等字段用于通知数据 * 将消息转换器抽象为接口，订阅器按 formatter 配置选择对应实现 * 更新配置校验以支持 crypto_strategy 格式化器，并补充单元测试
