后端UpdateAccountRequest.Status的oneof验证缺少error状态，
前端编辑表单也未处理error状态，导致编辑异常账号时无法保存

golangci-lint v2.7 was built with Go 1.25 and cannot lint Go 1.26
targets. v2.8+ added Go 1.26 support.

Fix/empty streamfix issue #791 

fix(ccswitch): improve import provider name and usage parsing

fix(account): preserve existing credentials when saving apikey accounts

GO-2026-4602 (os), GO-2026-4601 (net/url), GO-2026-4600 and
GO-2026-4599 (crypto/x509). The crypto/x509 fixes are only
available in go1.26.1+, not backported to go1.25.x.

对齐/v1/responses的Forward方法，修复两处不一致：
- 成功响应时从响应头提取OAuth账号的Codex使用量数据
- 非failover错误场景下应用管理员配置的错误透传规则

fix(usage): 修复用量查询 429 重试风暴，增加负缓存、请求去重与随机延迟

- Fix gofmt: align struct field comments in UsageCache, trim trailing
  whitespace on const comments
- Fix errcheck: use comma-ok on type assertion for singleflight result

Prevents 429 rate-limit retry storms and reduces upstream correlation risk
for Anthropic usage API queries.

Three changes:
1. Negative caching (1 min TTL) — 429/error responses are now cached,
   preventing every subsequent page load from re-triggering failed API calls.
2. singleflight dedup — concurrent requests for the same account are
   collapsed into a single upstream call, preventing cache stampede.
3. Random jitter (0–800 ms) — staggers multi-account cache-miss bursts so
   requests from different accounts don't hit upstream simultaneously with
   identical TLS fingerprints, reducing anti-abuse correlation risk.

When customErrorCodes is disabled or modelMapping is empty, explicitly
delete the fields inherited from currentCredentials spread to avoid
preserving stale values.

fix: Setup Token 账号使用真实 utilization 值替代状态估算

fix(openai): 修复 WS 模式下用量窗口不显示

从响应头 anthropic-ratelimit-unified-5h-utilization 获取并存储真实
utilization 值，解决进度条始终显示 0% 的问题。窗口重置时清除旧值，
避免残留上个窗口的数据。

When editing an apikey account, the credentials object was built from
scratch, causing fields like tier_id that are not exposed in the UI to
be silently dropped on save. Spread currentCredentials first so unknown
fields are retained, then let the known fields overwrite them.
