将 vansour/sub2api#1555 的 OpenAI compact 能力建模手工移植到当前 main：账号
级 compact 状态/auto-force_on-force_off 模式、compact-only 模型映射、调度器
tier 分层（已支持 > 未知 > 已知不支持）、管理后台 compact 主动探测，以及对应
i18n/状态徽章。普通 /responses 流量行为不变，无数据库迁移。

The hardcoded codex CLI version (0.104.0) causes upstream rejection
when using gpt-5.5 with compact, as the server treats the request
as an outdated client and returns 400/502.

Update codexCLIVersion, codexCLIUserAgent, and openAICodexProbeVersion
to 0.125.0 to match the current Codex CLI release.

- Drop SetAffiliateService setters and ProvideAuthService /
  ProvidePaymentService / ProvideUserHandler wrappers in favor of direct
  Wire constructor injection. AffiliateService has no back-edge to
  Auth/Payment/User, so the indirection was never required.
- Change RegisterWithVerification's variadic affiliateCode to a fixed
  parameter; adjust all call sites.
- Validate aff_code length and charset in BindInviterByCode before any
  DB lookup, eliminating timing-side-channel and useless DB roundtrips
  on malformed input.
- Make affiliate cache invalidation synchronous; surface Redis errors
  via the project logger instead of swallowing them in a detached
  goroutine.
- Add an integration test guarding cross-layer tx propagation in
  AccrueQuota and a unit test pinning the aff_code format rules.

Revert payment/wechat, sora/claude-max cleanup, fork-only migrations,
and cosmetic changes that were brought in by the release sync commit.
Keep only channel-monitor related improvements:
- PublicSettingsInjectionPayload named struct with drift test
- ChannelMonitorRunner graceful shutdown in wire
- image_output_price in SupportedModelChip
- Simplified buildSelfNavItems in AppSidebar
- Gateway WARN logs for 503 branches

- Extract PublicSettingsInjectionPayload named struct with drift test
- Add channel_monitor_default_interval_seconds to SSR injection
- Add image_output_price to SupportedModelChip
- Simplify AppSidebar buildSelfNavItems (admins see available channels)
- Add gateway WARN logs for 503 no-available-accounts branches
- Wire ChannelMonitorRunner into provideCleanup for graceful shutdown
- Add migrations 130/131 (CC template userid fix + mimicry field cleanup)
- Clean up fork-only features (sora, claude max simulation, client affinity)
- Remove ~320 obsolete i18n keys
- Add codexUsage utility, WechatServiceButton, BulkEditAccountModal
- Tidy go.sum

Service layer (payment_fulfillment_order_not_found_test.go):
- TestHandlePaymentNotification_UnknownOrder_ReturnsSentinel: in-memory
  sqlite ent client, query for a non-existent out_trade_no → errors.Is
  must recognise ErrOrderNotFound (handler relies on this to ack 200).
- TestHandlePaymentNotification_NonSuccessStatus_Skips: non-success
  notification short-circuits before DB lookup → nil error.
- TestErrOrderNotFound_DistinctFromOtherErrors: generic errors must not
  match the sentinel (prevents silently swallowing DB failures).

Handler layer (payment_webhook_handler_test.go):
- TestUnknownOrderWebhookAcksWithSuccess: locks the two ingredients the
  handleNotify ack path depends on — fmt.Errorf %w wrapping preserves
  errors.Is recognition, and writeSuccessResponse(stripe) returns an
  empty 200 body that Stripe treats as acknowledged.

Introduce a sentinel ErrOrderNotFound in the payment service layer so the
webhook handler can distinguish "the out_trade_no does not exist in our DB"
from other fulfillment failures, and downgrade the former to a WARN log +
success response.

Background
- Providers (Stripe, Alipay, Wxpay, EasyPay, ...) retry webhooks whenever
  we answer non-2xx. When a webhook endpoint is misconfigured (e.g. a
  foreign environment points at us) or our orders table has been wiped,
  we return 500 forever and the provider retries for days, spamming logs.
- The old code also collapsed "order not found" and "DB query failed" into
  the same branch — a DB blip would be reported as "order not found" and
  swallowed.

Service layer (payment_fulfillment.go)
- Add `var ErrOrderNotFound = errors.New("payment order not found")`.
- In HandlePaymentNotification, distinguish the two error paths:
  * dbent.IsNotFound(err) → wrap with ErrOrderNotFound so callers can
    errors.Is(...) it.
  * anything else → wrap the original err with %w so it still bubbles up
    as 500 and the provider retries (DB hiccup should be retried).

Handler layer (payment_webhook_handler.go)
- Before returning 500, check errors.Is(err, service.ErrOrderNotFound):
  emit a WARN (with provider / outTradeNo / tradeNo for discoverability),
  then call writeSuccessResponse so the provider sees its expected 2xx
  body (Stripe empty body / Wxpay JSON / others "success").
- Other errors retain the existing 500 behavior.

Monitoring note: because this path now swallows unknown-order webhooks
silently from the provider's perspective, the WARN log line is the only
signal. Alert on "unknown order, acking to stop retries" if you want
visibility into misrouted webhooks or accidental data loss.

The drift test referenced service.PublicSettingsInjectionPayload, a
named type introduced by a5b05538 but dropped when we cherry-picked
that commit into feat/channel-insights (we kept the inline struct from
HEAD to avoid pulling fork-only helpers from setting_service.go). The
test therefore could not compile. The 2 new public-settings fields
(channel_monitor_enabled, available_channels_enabled) are still covered
by manual wiring in GetPublicSettingsForInjection.

P0:

P1:
- ClearAll 按钮直连 DELETE API，带 loading 防重复
- 新增 GET /admin/users/:id/rpm-status 管理员 RPM 用量查询端点

优化:
- checkRPM 从级联互斥改为并行取最严，user.rpm_limit 作为全局硬上限始终生效
- Override/Group 变更后自动失效 auth cache
- fail-open 语义不变，Redis 故障不阻塞业务
