chore(backend): list_order迁移补齐+Task14类型修正落链+moments每页日志+MsgTypeParam派生+3处文档修正+Dockerfile打包migrations+DEPLOY补迁移步骤

- 9b0d0c133035: wechat_account.list_order 进迁移链(此前仅模型声明,
  干净库 /api/accounts 即 500);sa.inspect 幂等守卫兼容已手动加列的
  smoke.db
- fe63c6789e94(验证中发现的预存缺口,超出原清单): Task 14 的 5 列模型
  类型修正(4×URL String(1024)→Text, db_size Integer→BigInteger)从未落
  链——纯 alembic 新库会复活 >1KB 链接截断;对齐后干净库 alembic check
  全绿。SQLite message 表 batch 重建会掉 FTS 触发器+rowid 脱节(docstring
  记明 ensure_fts+rebuild_fts 修复,smoke.db 已修复验证)
- scrape_via_page: _iter_moments_pages 每页一行进度日志(镜像 _fetch_pages)
- messages: MsgTypeParam=Literal[tuple(_MSG_TYPE_FILTER)] 派生,杜绝
  双处罗列漂移(openapi enum 验证一致,492 绿含 422 行为)
- 文档: ChatGroup 复合PK docstring/groups room_id 多行表述/测试名去
  单行假设;Dockerfile 补 alembic.ini+migrations;DEPLOY 增「数据库
  迁移」节(新库/旧库stamp路径/回填脚本显式DB_URL)+运维表升级行
