Upstream removed sora feature (090_drop_sora.sql) but left i18n keys
and wire.go references. Clean up:
- Remove entire sora i18n block from en.ts and zh.ts (~190 lines)
- Remove sora nav key and unused 'data' settings tab key
- Remove sora_client_enabled from settings (fork-specific)
- Remove SoraMediaCleanupService from wire.go

The API client's error interceptor was dropping the reason and metadata
fields from backend error responses. This caused PaymentView to miss
specific error codes (TOO_MANY_PENDING, CANCEL_RATE_LIMITED) and fall
back to generic error messages.

Stripe payment path was setting expiresAt to empty string, causing
PaymentStatusPanel to fall back to hardcoded 30-minute default when
the popup redirect switches to the waiting view.

Backend:
- Parse EasyPay `payurl2` field, prefer H5 link on mobile
- Add `device=mobile` to EasyPay submit.php (popup) mode
- Expand isMobile detection keywords (add ipad/ipod)

Frontend:
- Add `isMobileDevice()` utility (userAgentData + UA regex)
- Mobile + pay_url: direct redirect instead of QR/popup
- Popup blocked fallback: auto-redirect when window.open fails
- Stripe WeChat Pay: dynamic client param (mobile_web vs web)

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)

The built-in payment system replaces the old external purchase subscription
iframe approach. Remove purchase_subscription_enabled/url from admin settings
interface and form defaults, as the Payment tab now handles this functionality.
Kept in stores/app.ts fallback to match backend DTO response structure.

- Add payment navigation to AppSidebar (user orders + admin payment menu group with collapse)
- Add 5 missing nav i18n keys (myOrders, orderManagement, paymentDashboard, paymentConfig, paymentPlans)
- Renumber payment migrations 090-100 → 092-102 to avoid conflict with upstream 090/091
- Remove non-payment sora_client_enabled change, restore upstream purchase_subscription fields
- Remove extra 'data' from SettingsTab type union

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

问题原因：
原本的 `style.css` 代码全局使用了 W3C 标准属性 (`scrollbar-width`)。而在 Chrome 121+ 以及 Safari 环境下，一旦匹配到 W3C 标准属性，浏览器就会放弃 WebKit 的定制样式，全面交由操作系统原生渲染。因为 macOS 原生的滚动条特性就是“不滚动时自动隐藏”，加之原本又配置了全局 hover 时才显色的透明度逻辑，最终导致在苹果系统下数据表常常无法明显看出横向滚动条。

修复方式：
1. 在 `style.css` 中增加 `@supports (-moz-appearance:none)`，将对全局 `scrollbar-width` 的干预严格隔离限制在 Firefox 浏览器内，防止误伤 Chrome 等 WebKit 系浏览器。
2. 移除旧版代码中对 `.table-wrapper` 直接定义的 `scrollbar-width` 和透明覆盖。
3. 在 `DataTable.vue` 内部，通过 `!important` 将 Webkit 专属定制外观（12px高度，实心圆角灰色轨道）的优先权推至最高，强制覆盖透明隐身规则。
4. 为底层 table 添加了 `min-w-max` 属性，强制阻止内容宽度受限于屏幕边界带来的收缩，充分保证合理超出范围而触发常驻横向溢出。

- Sync cc_version in x-anthropic-billing-header with the fingerprint
  User-Agent version, preserving the message-derived suffix
- Implement xxHash64-based CCH signing to replace the cch=00000
  placeholder with a computed hash
- Add admin toggle (enable_cch_signing) under gateway forwarding settings,
  disabled by default

The previous Sora removal missed several frontend references, causing
TypeScript build errors for sora_client_enabled and a missing SoraView.vue
import. Clean up all remaining Sora code from types, router, sidebar,
settings, store, and accounts API.

This component is used by SettingsView.vue for backup/data management.
It was mistakenly deleted as "Sora storage management" but contains
non-Sora backup functionality from upstream.

The options parameter only served to switch between 'openai' and 'sora'
platforms. With Sora removed, the parameter is unnecessary.

- Remove unused accessTokenInput ref from OAuthAuthorizationFlow
- Remove unused parsedSessionToken* computed and handleValidateSessionToken
- Prefix unused options parameter in useOpenAIOAuth

- Remove handleImportAccessToken event binding from CreateAccountModal
- Remove unused imports/variables from OAuthAuthorizationFlow (useAppStore,
  parsedAccessToken*, handleImportAccessToken)
- Remove unused oauthPlatform variable from useOpenAIOAuth composable

- GetGroupPlatforms failure now stores error-TTL cache and returns error (fail-close)
- Frontend group-to-channel conflict map loads all channels instead of current page only
- Toggle channel status reloads list when active filter would hide the changed item

P0-1: Credits degraded response retry + fail-open
- Add isAntigravityDegradedResponse() to detect transient API failures
- Retry up to 3 times with exponential backoff (500ms/1s/2s)
- Invalidate singleflight cache between retries
- Fail-open after exhausting retries instead of 5h circuit break

P1-1: Fix channel restriction pre-check timing conflict
- Swap checkClaudeCodeRestriction before checkChannelPricingRestriction
- Ensures channel restriction is checked against final fallback groupID

P1-2: Add interval pricing validation (frontend + backend)
- Backend: ValidateIntervals() with boundary, price, overlap checks
- Frontend: validateIntervals() with Chinese error messages
- Rules: MinTokens>=0, MaxTokens>MinTokens, prices>=0, no overlap

P2: Fix cross-platform same-model pricing/mapping override
- Store cache keys using original platform instead of group platform
- Lookup across matching platforms (antigravity→anthropic→gemini)
- Prevents anthropic/gemini same-name models from overwriting each other

Only display image count format when billing_mode is "image".
When channel has token pricing, show input/output/cache token details.
