feat(wx): 微信服务号消息接收回调 /wx/mp/callback（截图比价入口第一步）

- GET 接入验证（校验 signature → 原样返回 echostr），供公众平台配置服务器 URL
- POST 收消息（安全模式：msg_signature 验签 + AES-256-CBC 解密），图片消息用 PicUrl 落盘
- config 加 WX_MP_TOKEN / WX_MP_AES_KEY + wx_mp_callback_configured
- 识别平台订单/pending标记/openid↔device 绑定留后续

+
+覆盖 admin「比价记录」详情抽屉的「LLM 成本」展示分支:
+  • app_config.llm_token_price ← 写一条多模型单价(= 配置页「LLM 成本」卡片「已改」态,get_llm_prices 读它)
+  • comparison_record ← 造 5 条,逐条**复用生产的 compute_llm_cost + 与 _backfill_llm_calls 同款派生**

+    确保 mock 行 = 真实回填产出。5 条刻意覆盖:
+      ① 单模型真实样本(qwen3.5-flash ×4) → ¥0.006184(核对精确值)
+      ② 多模型(flash + plus)          → 快照含两个模型、各自 _source=per_model
+      ③ 未登记模型(deepseek-v3)        → 走 default,快照 _source=default

+      ⑤ 含 error 调用                    → error 那次跳过计费、retry_count+1
+
+记录挂到库里第一个真实用户(admin 列表能显示手机号);无用户则 user_id=NULL(孤儿行,admin 照样全看)。
+created_at 用北京 naive、最近几分钟内错开,详情列表倒序即 ①→⑤ 置顶。
