- Restore function deleted during cherry-pick conflict resolution
- Reset VERSION to upstream 0.1.112

- QuotaLimit changed to *int64 (null=unlimited, >0=limited)
- Add reset-usage endpoint (POST /admin/settings/web-search-emulation/reset-usage)
- Show quota usage in header always (collapsed and expanded)
- Add reset quota button in expanded provider view
- Quota input: empty=unlimited with ∞ placeholder, must be >0 if set
- Add email verification hint on balance notify card

The buttons were hidden because v-if only checked provider.api_key,
which is always empty for saved providers (backend sanitizes it).
Now also checks api_key_configured. Copy button is disabled when
no actual key is available (only configured placeholder shown).

M5: New composable frontend/src/composables/useQuotaNotifyState.ts
  - Replaces 9 individual refs in both Create/Edit modals with reactive state
  - Provides loadFromExtra/writeToExtra/reset helpers
  - Eliminates ~120 lines of duplicated code across the two modals

H14: Vue file length violations fixed
  - AdminPaymentPlansView.vue: 325 → 183 lines (extracted PlanEditDialog.vue)
  - QuotaLimitCard.vue: 327 → 268 lines (extracted QuotaDimensionRow.vue)
  - PlanEditDialog.vue: 181 lines (new, plan create/edit form)
  - QuotaDimensionRow.vue: 108 lines (new, single quota dimension row)

refactor: batch 3 — decompose CheckBalanceAfterDeduction, merge crossing checks, add QuotaNotifyConfig

M1: CheckBalanceAfterDeduction (63→18 lines) decomposed into:
    canNotifyBalance, resolveUserEffectiveThreshold, crossedDownward, dispatchBalanceLowEmail
M3: New Account.QuotaNotifyConfig(dim) method replaces 9 hardcoded getters
    (getters kept as thin wrappers for backward compatibility)
M4: checkQuotaDimCrossings + checkQuotaDimCrossingsFromState merged into one
    function taking pre-built []quotaDim; caller builds dims conditionally

H5: diffSettings now tracks 5 balance/quota notify fields in audit log
M15: log.Printf audit log migrated to slog.Info, removed "log" import
M14: New frontend/src/constants/account.ts with shared constants
     QuotaNotifyToggle.vue uses QUOTA_THRESHOLD_TYPE_FIXED/PERCENTAGE
L2: UsageTable.vue uses BILLING_MODE_TOKEN/IMAGE from billingMode.ts

fix: batch 1 audit fixes — quota SQL fixed mode, public recharge URL, WebSearch bool fallback, UpdatePlan validation

H1: incrementUsageBillingAccountQuota now uses shared dailyExpiredExpr/weeklyExpiredExpr
    constants (supporting fixed reset mode) instead of hardcoded '24 hours'/'168 hours'
H4: public settings endpoint now maps balance_low_notify_recharge_url
H6: GetWebSearchEmulationMode tolerates legacy bool values (true→enabled)
H7: UpdatePlan validates non-nil patch fields (rejects negative price, empty name, etc.)
H8: UsageTable accountBilled() helper with total_cost ?? 0 null guard
H9: AdminUsageLog TS type adds channel_id + billing_tier
M2: account.go "fixed" literals replaced with thresholdTypeFixed constant
M13: SystemSettings TS type adds web_search_emulation_enabled
UI: QuotaLimitCard title labels now use flex-1 to align with flex-1 input boxes

- EditAccountModal width changed from "normal" to "wide" (match CreateAccountModal)
- CreateAccountModal now passes all quota notify props to QuotaLimitCard
- QuotaLimitCard: when global notify disabled, hide title row, input takes full width
- Quota alert email: show remaining quota + threshold (fixed/$, percentage/%) instead of usage trigger point

- Quota alert email now shows account ID and platform
- Balance low email includes a "Top Up Now" button when recharge URL is configured
- New setting: balance_low_notify_recharge_url in admin settings

Threshold now represents remaining quota instead of usage amount:
- Fixed ($): threshold=400, limit=1000 → alert when remaining drops to $400
  (i.e., usage reaches $600)
- Percentage (%): threshold=30%, limit=1000 → alert when remaining drops
  to 30% (i.e., usage reaches $700)

Also:
- Rename 告警阈值 → 提醒阈值 in i18n
- Widen type dropdown to w-16 for proper $ / % display

Move QuotaNotifyToggle to the same row as the limit $ input for all
three dimensions (daily/weekly/total), significantly reducing card height.

- QuotaLimitCard: add collapse/expand toggle (chevron icon + click header)
- QuotaNotifyToggle: show $ or % suffix in threshold input
- Reduce vertical spacing between reset mode hint and notify toggle

- QuotaNotifyToggle: add $ or % suffix to threshold input based on type
- QuotaLimitCard: combine reset mode and notify toggle on same row
  to reduce vertical height for daily/weekly sections
- Remove redundant ml-4 indentation from QuotaNotifyToggle

Priority was wrong:
- Before: custom rules → LiteLLM (when ApplyPricingToAccountStats) → nil
- After:  custom rules → totalCost (when ApplyPricingToAccountStats) → LiteLLM → nil

When ApplyPricingToAccountStats is enabled, use the request's actual
client billing cost (before multiplier) as account_stats_cost, instead
of recalculating from LiteLLM per-token prices which produced incorrect
values for per-request billing mode.

LiteLLM model pricing is now the final fallback (priority 3), used only
when neither custom rules nor ApplyPricingToAccountStats apply.

The field was present in SystemSettings response DTO and service layer
but missing from:
- UpdateSettingsRequest (admin handler) - saves were silently ignored
- GET/PUT response mapping in admin handler
- UpdateSettingsRequest (non-admin dto)

This caused the toggle to always revert to off after saving.

QuotaLimitCard now requires quotaNotifyGlobalEnabled prop to control
visibility of QuotaNotifyToggle components. When the global account
quota notification is disabled in admin settings, per-account threshold
toggles are hidden in both Edit and Create account modals.

- Move sanitizeEmailHeader to SendEmailWithConfig entry point, covering all
  email senders (verify code, password reset, ops alerts, notifications)
- Add panic recovery to UpdateBalance goroutine
- Fix stale comment in getAccountQuotaNotifyEmails (email="" no longer used)
- Log error instead of silently discarding verifyNotifyCode cache update failure

P0: fix wildcard matching test assertion (config order, not longest prefix)
P0: add TotalRecharged to auth cache snapshot (v5) for percentage threshold
P1: move pricing rules into per-platform sections in ChannelsView
P1: populate account name cache when editing existing channel rules
P1: sanitize email subject headers to prevent SMTP injection
P1: make Redis INCR+EXPIRE idempotent for rate limiting
P1: deep copy FeaturesConfig in Channel.Clone()
P2: clean up stale email="" placeholder comments
P2: replace log.Printf with slog in email_service.go

- 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

Backend:
- Define OrderTypeBalance/Subscription, EntityStatusActive, DeductionType*,
  NotificationStatus* constants in payment/types.go
- Replace all magic strings in payment_order, payment_fulfillment, payment_refund
- Add local constants in easypay.go (tradeStatusSuccess, signTypeMD5)
- Add 27 unit tests for load balancer (filterByLimits, pickLeastAmount,
  getInstanceChannelLimits, startOfDay)

Frontend:
- Remove all `any` types in SettingsView.vue (18 catch blocks + 1 payload)
- Fix bare catch blocks in PaymentResultView, PaymentView
- Add `unknown` type annotation to all catch blocks

chore: bump version to 0.1.108.140

The paginated List query was selecting 9 columns but scanning 10 fields,
missing c.features. GetByID and ListAll already included it correctly.
