feat(usage): 记录并展示失败请求(用户端+管理端)

- 记录失败请求并在用户端/管理端展示;分类下拉改用统一 Select 组件
- 模型过滤改后端 ILIKE 模糊匹配;新增「Key 名称」列(含已删除标记)与按 Key 过滤;时间列移至末列
- 用户可见「已删除 key 失败请求」:OpsErrorLogFilter 加 MatchDeletedKeyOwner,用户侧归属
  放宽为 (user_id OR deleted_key_owner_user_id),让 key 原所有者能看到删除 key 后继续请求
  导致的认证失败记录(他人仍 NotFound,不泄露存在性)
- 迁移 148:ops_error_logs 用户+时间索引
