b2e379cf 引入的 BufferedResponseAccumulator 已修复了 chat_completions
非流式路径和 responses OAuth 非流式路径，但遗漏了 Anthropic /v1/messages
非流式路径 (handleAnthropicBufferedStreamingResponse)。

当客户端请求 stream=false 且模型开启思考时，上游 response.completed
终态事件的 output 字段可能为空，实际 message 内容通过
response.output_text.delta 增量事件下发。旧代码只读终态事件的 Response，
导致客户端收到的 content 字段为空 ([{"type":"text"}])。

本 commit 将 b2e379cf 的相同修复模式镜像到 Anthropic 路径：在 SSE 扫描
过程中用 BufferedResponseAccumulator 累积 delta 内容，终态 output 为空
时通过 SupplementResponseOutput 补充重建。

同时修复 handleAnthropicBufferedStreamingResponse 遗漏 response.done
事件类型的问题，与 chat completions 路径保持一致，避免上游发送
response.done 时 handler 认不出终态事件、最终返回 502 的潜在问题。

BufferedResponseAccumulator 已在 chatcompletions_responses_test.go 有
完整单元测试覆盖（TextOnly/ToolCalls/Reasoning/Mixed/SupplementEmpty/
NoSupplementWhenOutputExists/EmptyDeltas/IgnoresNonFunctionCallItems），
本次复用相同累加器无需新增测试。

When an Anthropic API key's credit balance is depleted, the upstream
returns HTTP 400 with message containing "credit balance". Previously,
the 400 handler only checked for "organization has been disabled",
so credit-exhausted accounts kept being scheduled — every request
returned the same error.

Treat this case identically to 402 (Payment Required): call
handleAuthError → SetError to stop scheduling the account until
an admin manually recovers it after topping up credits.

Closes #1586

Backend:
- Split payment_order.go (546→314 lines) into payment_order_lifecycle.go
- Replace magic strings with constants in factory, easypay, webhook handler
- Add rate limit/validity unit constants in payment_order_lifecycle, payment_service
- Fix critical regression: add PaymentEnabled to GetPublicSettings response
- Add missing migration 099_fix_migrated_purchase_menu_label_icon.sql

Frontend:
- Fix StripePopupView.vue: replace `as any` with typed interface, use extractApiErrorMessage
- Fix AdminOrderTable.vue: replace hardcoded column labels with i18n t() calls
- Fix SubscriptionsView.vue: replace hardcoded Today/Tomorrow with i18n
- Extract duplicate statusBadgeClass/canRefund/formatOrderDateTime to orderUtils.ts
- Add missing i18n keys: common.today, common.tomorrow, payment.orders.orderType/actions
- Remove dead PurchaseSubscriptionView.vue (replaced by PaymentView)

Add a full payment and subscription system supporting EasyPay (Alipay/WeChat),
Stripe, and direct Alipay/WeChat Pay providers with multi-instance load balancing.

10KB is too aggressive for modern LLM API requests where conversation
context routinely exceeds 1MB. This causes error logs to contain only
a minimal placeholder, making it impossible to debug upstream failures.

256KB retains enough context for effective debugging while the existing
multi-pass trimming logic handles larger payloads gracefully.

commit f3aa54b7 的 rewriteSystemForNonClaudeCode 未能通过 Anthropic 第三方检测，
根因是两个关键信号与真实 Claude Code 不一致：

1. anthropic-beta 头缺少 claude-code-20250219：伪装路径主动将该 beta
   加入 drop set 并移除，但 Anthropic 依赖此 beta 识别 Claude Code 请求。
   修复：非 haiku 模型的伪装请求强制包含 claude-code beta。

2. system 字段使用 string 格式而非 array+cache_control：真实 Claude Code
   始终以 [{type,text,cache_control:{type:"ephemeral"}}] 发送 system，
   string 格式成为第三方检测信号。
   修复：rewriteSystemForNonClaudeCode 改为注入 array 格式。

附带调整：stripSystemCacheControl 按 system 是否被重写动态决定，
重写时保留 CC prompt 的 cache_control，未重写时（haiku/已含CC前缀）
保持原有剥离行为。

Anthropic近期引入基于system参数内容的第三方应用检测机制，原有的前置追加
Claude Code提示词策略无法通过检测（后续内容仍为非Claude Code格式触发429）。

新策略：对非Claude Code客户端的OAuth/SetupToken账号请求，将system字段
完整替换为Claude Code标识提示词，原始system内容作为user/assistant消息对
注入messages开头，模型仍接收完整指令。

仅影响/v1/messages路径，chat_completions和responses路径保持原有逻辑不变。
真正的Claude Code客户端请求完全不受影响（原样透传）。

- 20 unit tests for deriveOpenAIContentSessionSeed covering:
  - Empty/nil inputs, model-only, stable across turns
  - Different model/system/first-user produce different seeds
  - Tools, functions, developer role, structured content
  - Responses API: input string, input array, instructions, input_text typed items
  - JSON canonicalization (whitespace/key-order insensitive)
  - Prefix presence, empty tools ignored, messages preferred over input
- 3 integration tests for GenerateSessionHash content fallback:
  - Content fallback produces stable hash
  - Explicit signals override content fallback
  - Empty body still returns empty hash

When no explicit session signals (session_id, conversation_id, prompt_cache_key)
are provided, derive a stable session seed from the request body content
(model + tools + system prompt + first user message) to enable sticky routing
and prompt caching for non-Codex clients using the Chat Completions API.

This mirrors the content-based fallback already present in GatewayService.
GenerateSessionHash, adapted for the OpenAI gateway's request formats (both
Chat Completions messages and Responses API input).

JSON fragments are canonicalized via normalizeCompatSeedJSON to ensure
semantically identical requests produce the same seed regardless of
whitespace or key ordering.

Closes #1421

refactor(channel): split long functions, extract shared validation, move billing validation to service

- Split Update (98→25 lines), buildCache (54→20 lines), Create (51→25 lines)
  into focused sub-functions: applyUpdateInput, checkGroupConflicts,
  fetchChannelData, populateChannelCache, storeErrorCache, getOldGroupIDs,
  invalidateAuthCacheForGroups
- Extract validateChannelConfig to eliminate duplicated validation calls
  between Create and Update
- Move validatePricingBillingMode from handler to service layer for
  proper separation of concerns
- Add error logging to IsModelRestricted (was silently swallowing errors)
- Add 12 new tests: ToUsageFields, billing mode validation, antigravity
  wildcard mapping isolation, Create/Update mapping conflict integration

当上游返回SSE格式响应(如sub2api链路)时，API Key账号的非流式路径
未检测SSE，导致终态事件中空output直接透传给客户端。

- 将Content-Type SSE检测从仅OAuth扩展至所有账号类型
- 重命名handleOAuthSSEToJSON为handleSSEToJSON（无OAuth专属逻辑）
- 为透传路径新增handlePassthroughSSEToJSON，支持SSE转JSON及空output重建

When multiple goroutines/workers concurrently refresh the same OAuth token,
the first succeeds but invalidates the old refresh_token (rotation). Subsequent
attempts using the stale token get invalid_grant, which was incorrectly treated
as non-retryable, permanently marking the account as ERROR.

Three complementary fixes:
1. Race-aware recovery: after invalid_grant, re-read DB to check if another
   worker already refreshed (refresh_token changed) — return success instead
   of error
2. In-process mutex (sync.Map of per-account locks): prevents concurrent
   refreshes within the same process, complementing the Redis distributed lock
3. Increase default lock TTL from 30s to 60s to reduce TTL-expiry races
