- Change balance_notify_extra_emails and account_quota_notify_emails
  from []string to []NotifyEmailEntry{email, disabled, verified}
- Add per-email enable/disable toggle for both user and admin notifications
- Add PUT /user/notify-email/toggle API endpoint
- Fix critical bug: API key auth cache snapshot missing balance notify
  fields (Email, Username, BalanceNotifyEnabled, etc.), causing
  notifications to never fire on cached request paths
- Bump cache snapshot version 3→4 to invalidate stale entries
- Add SQL migration 104 to convert old format data
- Backward compatible: parseNotifyEmails auto-detects old/new format
- User balance notify: max 3 emails (primary + 2 extra)
- Admin quota notify: unlimited emails, each with toggle

Replace blur-based auto-save with an explicit Save button so users
know when their threshold is persisted. Shows success toast on save.

- Show system default threshold as placeholder in custom threshold input
- Display user's primary email with "Primary" badge
- Support adding multiple pending emails before verification
- Each pending email has independent send/verify/resend flow
- Expose balance_low_notify_threshold in PublicSettings API
- Clean up timers on unmount to prevent leaks

- Fix GetByKeyForAuth missing user.FieldEmail and user.FieldUsername (notifications sent to empty address)
- Guard against empty email in collectBalanceNotifyRecipients
- Remove non-atomic TotalRecharged read-modify-write in admin balance adjustment
- HTML-escape userName/siteName/accountName in notification email templates
- Fix timer leak in ProfileBalanceNotifyCard (add onUnmounted cleanup)
- Add warning log on websearch proxy URL resolution failure

- Add global toggle for account quota notification in admin settings
- Add percentage-based threshold type for per-account quota alerts
- Hide balance notify card on user profile when global toggle is off
- Expose balance_low_notify_enabled and account_quota_notify_enabled in PublicSettings
- Add threshold type (fixed/percentage) to QuotaNotifyToggle with $ / % switcher

- API Key show/copy buttons moved inside input field (inline icons)
- Proxy selector and test button on same row to save vertical space
- Test opens a dialog modal instead of inline display
- Hide all websearch config in channels/accounts when global toggle is off

- Fix accountCost calculation in finalizePostUsageBilling to match
  postUsageBilling (always multiply by AccountRateMultiplier)
- Use strings.EqualFold for email dedup in collectBalanceNotifyRecipients
- Extract CheckAccountQuotaAfterIncrement into smaller functions:
  buildQuotaDims + asyncSendQuotaAlert (< 30 lines each)
- Add "not splittable" comments for HTML template functions
- Extract QuotaNotifyToggle.vue sub-component to reduce
  QuotaLimitCard.vue from 404 to 339 lines

- User balance low notification: email alert when balance drops below
  configurable threshold (user email + verified extra emails)
- Account quota notification: broadcast email to admin-configured
  recipients when daily/weekly/total quota usage exceeds alert threshold
- Admin settings: global enable/disable, default threshold, quota
  notification email list (Email Settings tab)
- User profile: enable/disable, custom threshold, add/remove extra
  notification emails with verification code flow
- Account quota: per-dimension alert toggle and threshold in quota
  control card
- Trigger logic: first-crossing only (old >= threshold && new < threshold
  for balance; old < threshold && new >= threshold for quota), naturally
  prevents duplicate notifications without Redis dedup

Inject web search capability for Claude Console (API Key) accounts that
don't natively support Anthropic's web_search tool. When a pure
web_search request is detected, the gateway calls Brave Search or Tavily
API directly and constructs an Anthropic-protocol-compliant SSE/JSON
response without forwarding to upstream.

Backend:
- New `pkg/websearch/` SDK: Brave and Tavily provider implementations
  with io.LimitReader, proxy support, and Redis-based quota tracking
  (Lua atomic INCR + TTL, DECR rollback on failure)
- Global config via `settings.web_search_emulation_config` (JSON) with
  in-process cache + singleflight, input validation, API key merge on
  save, and sanitized API responses
- Channel-level toggle via `channels.features_config` JSONB column
  (DB migration 101)
- Account-level toggle via `accounts.extra.web_search_emulation`
- Request interception in `Forward()` with SSE streaming response
  construction using json.Marshal (no manual string concatenation)
- Manager hot-reload: `RebuildWebSearchManager()` called on config save
  and startup via `SetWebSearchRedisClient()`
- 70 unit tests covering providers, manager, config validation,
  sanitization, tool detection, query extraction, and response building

Frontend:
- Settings → Gateway tab: Web Search Emulation config card with global
  toggle, provider list (add/remove, API key, priority, quota, proxy)
- Channels → Anthropic tab: web search emulation toggle with global
  state linkage (disabled when global off)
- Account Create/Edit modals: web search emulation toggle for API Key
  type with Toggle component
- Full i18n coverage (zh + en)

Closes #1607

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。

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.

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)

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

- 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.
