feat(mcp): properties 流导出归属字段 supervisor_id / agent_id

问题：m0.properyt 有 supervisorId（所属销售）与 agentId（所属代理商），
但 properties 变更流只导出 10 个字段，下游拿不到归属，物业建出的客户无负责人。

改动：
- SyncChangeSchemas.PropertyChange 增加 supervisor_id、agent_id
- PropertiesSyncEntity.toItem 传出 row.getSupervisorId()/getAgentId()

下游：网关透传 → CRM 按 user 映射解析为负责人（解析不到保持公海）。
