Replace icon-based language options with plain text labels in both the
header dropdown and preferences settings to keep the UI clean and
avoid potential controversies. Remove unused country-flag-icons dependency.

改变端点映射文案

fix: 修复模型管理"参与官方同步"与"状态"开关无法保存的问题

fix: 如果模型管理有自定义配置则不合并默认配置

feat: make 5m cache-creation ratio configurable

feat: /v1/messages -> /v1/responses

fix: 补全 streaming message_delta 事件缺失的 input_tokens 和 cache 相关字段

fix: 使用openai兼容接口调用部分渠道在最终端点为claude原生端点下还是走了openai扣减input_token的逻辑

feat: channel test with stream=true

# Conflicts:
#	service/openaicompat/chat_to_responses.go

fix: add paragraph breaks between reasoning summary chunks

fix: Claude stream block index/type transitions

feat(oauth): implement custom OAuth provider

feat: Force beta=true parameter for Anthropic channel

feat: add Codex channel disclaimer (i18n, OpenAI terms)

Modified the formatUserLogs function to include a startIdx parameter, allowing for more flexible log ID assignment. Updated calls to this function in GetLogByTokenId and GetUserLogs to pass the appropriate starting index.

当上游为 AWS Bedrock 时，message_delta 的 usage 可能缺少 input_tokens、
cache_creation_input_tokens、cache_read_input_tokens 等字段，导致与原生
Anthropic 格式不一致。从 message_start 积累的 claudeInfo 中补全这些字段后
重新序列化，确保客户端收到一致的 usage 格式。

✨ chore: Improve subscription billing fallback and UI states

🔔 feat: Add subscription-aware quota notifications and update UI copy

Routes quota alerts through a subscription-specific check when billing from subscriptions, preventing wallet-based thresholds from triggering false warnings.
Updates the notification settings description and localization keys to clarify that both wallet and subscription balances are monitored.

Aligns the error variable types in the subscription-first path so that quota fallback checks use the correct NewAPIError.
This prevents build failures and preserves the intended wallet fallback when subscription pre-consume returns an insufficient quota error.

Add a lightweight active-subscription check to skip subscription pre-consume when none exist, reducing unnecessary transactions and locks. In the subscription UI, disable subscription-first options when no active plan is available, show the effective fallback to wallet with a clear notice, and distinguish “invalidated” from “expired” states. Update i18n strings across supported locales to reflect the new messages and status labels.

refactor: 抽象统一计费会话 BillingSession

✨ refactor(wallet): Top-up layout to embed subscription plans into the recharge card tabs

- Defaulting to subscriptions when available and avoiding initial flash when no plans exist.
- Adjust the wide-screen layout to place wallet and invite sections side by side, simplify the subscription header and controls, and add padding to prevent card borders from clipping.
- Update related i18n strings by adding the new tab label and removing the obsolete subscription blurb.

- Settle 部分失败保护：新增 fundingSettled 标记，资金来源提交后
  令牌调整失败不再导致 Refund 误退已结算的资金
- 订阅多扣费修复：trySubscription 传 subConsume 而非 preConsumedQuota
  给 preConsume，保证三者（amount/preConsume/FinalPreConsumedQuota）一致
- 令牌回滚错误记录：preConsume 中 funding 失败时令牌回滚错误不再丢弃
- 移除钱包路径死代码：用户额度不足的 strings.Contains 匹配不可能命中
- WalletFunding.Refund 不重试：IncreaseUserQuota 非幂等，重试会多退

将散落在多个文件中的预扣费/结算/退款逻辑抽象为统一的 BillingSession 生命周期管理：

- 新增 BillingSettler 接口 (relay/common/billing.go) 避免循环引用
- 新增 FundingSource 接口 + WalletFunding / SubscriptionFunding 实现 (service/funding_source.go)
- 新增 BillingSession 封装预扣/结算/退款原子操作 (service/billing_session.go)
- 新增 SettleBilling 统一结算辅助函数，替换各 handler 中的 quotaDelta 模式
- 重写 PreConsumeBilling 为 BillingSession 工厂入口
- controller/relay.go 退款守卫改用 BillingSession.Refund()

修复的 Bug：
- 令牌额度泄漏：PreConsumeTokenQuota 成功但 DecreaseUserQuota 失败时未回滚
- 订阅退款遗漏：FinalPreConsumedQuota=0 但 SubscriptionPreConsumed>0 时跳过退款
- 订阅多扣费：subConsume 强制为 1 但 FinalPreConsumedQuota 不同步
- 退款路径不统一：钱包/订阅退款逻辑现统一由 FundingSource.Refund 分派
