feat(debug-trace): 调试链接权限 + trace_url 落库与按权限下发

- user 加 debug_trace_enabled、comparison_record 加 trace_url
- 迁移 f8d3b1e60a27：加两列，down_revision 用 tuple 顺带合并既存双 head(invite_fingerprint_table + 044dce6e9b1f)
- UserOut 加 debug_trace_enabled → /me 与登录响应带出
- ComparisonRecordIn/Out 加 trace_url；upsert 落库
- /compare/records 列表与详情按 user.debug_trace_enabled 下发；详情连 raw_payload 里那份一并抹掉，防权限绕过
- admin 加 POST /users/{id}/debug-trace（operator + 审计），列表带该字段

+"""add user.debug_trace_enabled + comparison_record.trace_url（并合并既存双 head）
+
+调试链接权限功能：
+  - user.debug_trace_enabled：运营后台给指定用户开「复制调试链接」权限
+  - comparison_record.trace_url：比价记录页「复制调试链接」的数据（pricebot done 帧给，
+    dir 名含落盘时分秒、前端/server 拼不出，必须落库）
+
+⚠️ 本迁移 down_revision 是 **tuple**，同时合并了 clone 时 main 上既存的双 head：
+  - invite_fingerprint_table  （#31 被邀请人列表 + 指纹归因 那条线）
+  - 044dce6e9b1f              （merge_ad_feed_reward_session + withdraw_safety_indexes）
+  这两个头平行未合并，`alembic upgrade head` 会报 Multiple heads。本迁移顺手收口成单 head。
+  若想把「合并双 head」与「加列」拆开，可改成：先一个纯 merge 迁移、再一个加列迁移。
