📝 变更描述 / Description

订阅计费时不应再叠乘分组倍率，否则高分组（如 vip=2）会加速消耗订阅额度，相当于多扣。

修复：

• 资金来源实际走 订阅 时，分组倍率固定为 1（按模型基础价扣订阅池）
• 预扣额度按原分组倍率还原：preConsume / groupRatio
• 同步 PriceData、阶梯计费 snapshot，保证结算/日志一致
• 订阅预扣失败回退钱包时，恢复原分组倍率
• Realtime WSS、任务按 token 重算等路径对订阅同样按倍率 1
• VERSION：20260718 → 20260719

未改： 钱包计费仍使用正常分组倍率。

• 非重复提交: 已搜索 Issues / PRs（请自行再确认）。
• Bug fix 说明: 订阅叠分组倍率导致多扣，属计费错误。
• 变更理解: 已理解影响范围（订阅路径预扣/结算/任务重算）。
• 范围聚焦: 以订阅倍率为核心；若相对 origin/main 含 status-code 映射 commit，请在 review 时一并确认。
• 本地验证: 单测 TestAdjustQuotaToSubscriptionBaseRate、TestApplyAndRestoreSubscriptionBaseGroupRatio 通过；go build ./service 通过。
• 安全合规: 无敏感凭据。

Walkthrough

This PR adds configurable upstream status-code response mappings, group-scoped subscription billing, cache-token analytics, a home notice dialog, and related API, UI, localization, persistence, and build configuration updates.

Changes

Status-code response mapping

Layer / File(s)	Summary
Error contracts and mapping engine types/error.go, service/error.go, dto/task.go	Errors retain original status codes and can apply mapped status, message, type, and code values to API and task responses.
Relay and channel integration controller/relay.go, controller/channel.go, middleware/distributor.go, model/channel.go	Channel mappings are validated, propagated through context, applied to relay responses and logs, and excluded from sensitive-field classification.
Channel configuration UI web/default/src/features/channels/..., web/default/src/i18n/locales/*	Channel forms validate, persist, display, and translate status-code response mappings.

Group-scoped subscription billing

Layer / File(s)	Summary
Plan and subscription enforcement model/subscription.go, model/main.go, controller/subscription.go	Plans and purchased subscriptions store normalized allowed groups, validate configured groups, and restrict subscription eligibility by using group.
Billing integration service/billing_session.go, service/funding_source.go, service/quota.go, service/task_billing.go	Subscription billing uses a base group ratio, passes the active using group through pre-consumption, and restores wallet pricing when subscription pre-consumption fails.
Subscription management UI web/default/src/features/subscriptions/..., web/classic/src/components/table/subscriptions/...	Subscription forms, purchase dialogs, and tables support selecting and displaying billing groups.

Cache analytics

Layer / File(s)	Summary
Aggregation and API exposure model/log.go, controller/log.go, controller/usedata.go, router/api-router.go	Cache tokens and hit rates are calculated from consumption logs and exposed through statistics and per-model cache endpoints.
Dashboard and usage displays web/default/src/features/dashboard/..., web/default/src/features/usage-logs/...	Dashboard cards, log statistics, token breakdowns, and log rows display cache hit-rate metrics using normalized input-token semantics.
Cache calculation tests model/log_cache_test.go	Tests cover Anthropic semantics, normalized total input, per-model aggregation, cache tokens, and hit-rate calculations.

Home notices and supporting configuration

Layer / File(s)	Summary
Home notice dialog web/default/src/features/home/...	The custom home URL branch renders a dialog containing notice markdown and announcement timeline tabs.
Build and release settings Dockerfile, VERSION, .gitignore, web/.npmrc, web/classic/rsbuild.config.ts	Container module fetching, Debian package sources, version metadata, ignored tooling output, npm registry selection, and Classic Web date-fns resolution are updated.

Poem

I’m a rabbit with mappings to share,
Cache-rate carrots float through the air.
Groups guide billing, notices gleam,
Errors now follow a mapped-upstream dream.
Hop, hop—builds retry bright,
And dashboards show cache light!
