feat(test,export,headers): 模型测试复用统一运行时、实时进度展示、导出增强与请求头大小写保留

- 模型测试 failover 从手动 FailoverEngine 改为 TaskService.execute_sync_candidates 统一运行时
- 前端新增实时 trace 轮询进度展示（候选状态、测试账号、进度条）
- 用户导出/导入支持明文 Key 优先（版本升至 1.2），新增 email_verified 字段
- SENSITIVE_CREDENTIAL_FIELDS 统一到 provider_ops/types.py，补充 refresh_token
- 请求头大小写保留机制（resolve_header_name_case + HeaderBuilder.add 语义修改）
- Codex envelope 移除合成头部，保留客户端原始请求头
- endpoint_checker 支持自定义超时透传
- 新增 x-forwarded-scheme 到上游丢弃头部列表
