+-- RPC: rpc_delivery_* homecare actions
+-- Version: v1
+-- Purpose: 为 delivery 页面当前 api/delivery.uts 已固定的 rpc_delivery_* 契约补齐 SQL 端实现。
+-- Notes:
+-- 1. 优先兼容 ec/hc 新链，检测不到表或执行失败时回退 hss 旧链。
+-- 2. 返回 JSON 结构直接对齐 delivery/types/delivery.uts。
+-- 3. message_list 与 record_list 采用最小可用实现，避免前端继续落入 fallback。
