down_revision 之前误写为文件名 '052_diagnostic_queue_quiz_closing'，
应为 052 迁移的实际 revision id '052_diag_queue_quiz'。

影响范围：
- alembic history 直接抛 KeyError: '052_diagnostic_queue_quiz_closing'
- 任何 alembic upgrade / stamp head 操作均无法解析完整链
- 之前未被发现的根因：生产 alembic_version 长期停在 052，从未尝试解析后续链

验证（生产环境 2026-08-03 17:03 P1 治理任务）：
- 修复前：alembic history → KeyError
- 修复后：052 → 053 → 054 → 055 → 056(moderation) → 057 链完整解析
- alembic stamp 057_troubleshooting_templates 已成功执行
- 数据库实际状态确认：conversations.is_archived / messages.reply_source /
  quick_rules / sensitive_words / privacy_patterns / moderation_logs /
  troubleshooting_templates 均已存在，迁移链与数据库一致
