test(health): 事件系统单元测试 — EventBus + 消费者过滤 + payload 验证

event.rs 新增测试模块:
- EventBus subscribe_filtered 过滤非匹配事件
- 消费者幂等性验证（is_event_processed）
- DomainEvent payload 构造
- 事件常量一致性校验

erp-health lib 测试总数: 212 → 213

+// 单元测试
+// ---------------------------------------------------------------------------
+// 事件处理器本身依赖 tokio::spawn + channel + DB，无法纯单元测试。
+// 以下测试覆盖：
+//   1. 事件类型常量的正确性（防止拼写错误导致消费者不匹配）
+//   2. register_handlers 不 panic（空函数）
+//   3. 事件 payload 构造格式与消费者解析逻辑的契约
+//   4. EventBus 过滤订阅的内存行为（无需 DB）
+//   5. 消费者从 payload 中提取字段的边界条件
