perf(storage): 极简化任务历史并增加保留治理

停止持久化 provider 原始响应、兼容响应快照、attempt/event/outbox 重复 JSON，并由标准任务结果动态生成 Kling/Keling/Volces 兼容响应。

增加事件去重与预算、极简 callback 投递、7/30 天分批清理、安全删除条件、并发迁移索引及可实际恢复的任务域排除备份。历史清理默认关闭，待兼容协议和异步恢复在线验证后单独启用。

验证：Go 全量测试与 go vet、PostgreSQL 18 集成与实际备份恢复、迁移安全测试、bash -n、ShellCheck、Compose 配置和人工发布脚本测试均通过。
