Align struct field assignments and fix indentation detected by
golangci-lint v2.9's gofmt checker.

The recent upstream commit added allow_messages_dispatch to the Group
DTO but did not update the API contract test expectation.

Extend the existing total quota limit with daily and weekly periodic
dimensions. Each dimension is independently configurable and uses lazy
reset — when the period expires, usage is automatically reset to zero on
the next increment. Any dimension exceeding its limit will pause the
account from scheduling.

Backend:
- Add GetQuotaDailyLimit/Used, GetQuotaWeeklyLimit/Used, HasAnyQuotaLimit
- Rewrite IncrementQuotaUsed with atomic CTE SQL for 3-dimension update
- Rewrite ResetQuotaUsed to clear all dimensions and period timestamps
- Update postUsageBilling to use HasAnyQuotaLimit()
- Preserve daily/weekly used values on account edit

Frontend:
- Refactor QuotaLimitCard from single v-model to 3-dimension props
- Add QuotaBadge component for compact D/W/$ display
- Update AccountCapacityCell with per-dimension badges
- Update Create/Edit modals with daily/weekly quota fields
- Update AccountActionMenu hasQuotaLimit to check all dimensions
- Add i18n strings for daily/weekly/total quota labels

- 移除staticcheck 470+冗余检查项，all已包含全部
- unused: generated-is-used改为true，跳过ent 13万行生成代码分析
- unused: exported-fields-are-used改为true，避免全项目导出字段引用追踪
- unused: field-writes-are-uses改为true

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

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 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.

抽取共享的用户分组专属倍率解析器，统一缓存、singleflight 与回退逻辑。\n\n让 OpenAI 独立计费链路复用专属倍率解析，修复 usage 记录与实际扣费未命中用户专属倍率的问题。\n\n补齐 OpenAI 计费与解析器单元测试，并修复全量回归中暴露的 lint 阻塞项。\n\nCo-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

commit 80ae592c 引入 lite 模式优化首次加载性能，但将窗口费用查询也一起跳过了。
commit 491a7444

 尝试用 30 秒快照缓存修复，但缓存过期后问题复现。

移除窗口费用查询的 lite/非 lite 区分，始终执行 PostgreSQL 聚合查询。
同时删除不再需要的 account_window_cost_cache.go 文件。
