refactor: 清理未使用参数、移除死代码、聚焦电商核心模块

主要变更概述:
================

1. 清理未使用的函数参数 (TypeScript noUnusedParameters)
------------------------------------------------------
- AppShell.tsx: 移除未使用的 backendHealth prop 及 ServerConnectionHealth 导入
- canvasUtils.ts: 移除 resolveWorkflowVideoModel 的 workflowModel 参数
- canvasWorkflowDeserialize.ts: 同步更新调用方
- CanvasPage.tsx: 移除 resolveWorkflowVideoModel 未使用导入
- HomePage.tsx: 移除 onOpenTokenMonitor、onOpenImageTool 未使用 props
- ToolboxSection.tsx: 移除 onOpenImageTool 未使用 prop 及 WebImageWorkbenchTool 类型导入
- ScriptTokensPage.tsx: 移除 formatReportMarkdown 的 script 参数，更新 2 处调用
- TokenUsagePage.tsx: 移除 onOpenImageTool、onSelectView 未使用 props
- WorkbenchPage.tsx: 移除 renderComposerToolbar 的 showStop 参数，更新 2 处调用

2. 移除未使用的模块和死代码
--------------------------
删除以下未在电商模块中使用的功能模块:
- 画布模块 (canvas/): CanvasPage, canvasUtils, canvasWorkflow* 等
- 主页模块 (home/): HomePage, ToolboxSection, WelcomeSplash 等
- 工作台模块 (workbench/): WorkbenchPage, ConversationSidebar 等
- 社区模块 (community/, community-review/)
- 数字人模块 (digital-human/)
- 图片工作台 (image-workbench/)
- 其他独立工具页: agent, assets, beta-applications, character-mix,
  compliance, dialog-generator, more, profile, provider-health,
  report, resolution-upscale, script-tokens, settings, size-template,
  subtitle-removal, watermark-removal

3. 移除未使用的公共组件
----------------------
- AnimatedPanel, BeforeAfterCompare, BetaApplicationModal
- CookieConsentBanner, DropZone, EmptyState, NotFoundPage
- NotificationCenter, OnboardingTour, OptimizedImage
- PageTransition, RechargeModal, ShellIcon, Skeleton
- StudioToolLayout, TaskStatusBar, WorkspacePageShell

4. 移除未使用的 API 客户端
--------------------------
- betaApplicationClient, communityClient, conversationClient
- draftClient, modelCapabilitiesClient, notificationClient
- projectTaskClient, providerHealthClient, publicConfigClient
- referenceUploadService, reportClient, scriptEvalClient
- uploadWithProgress

5. 移除未使用的工具函数和 hooks
-------------------------------
- utils/: imageModelVisibility, mentionTrigger, modelOptions,
  ossImageOptimize, toolPageUtils
- hooks/: useGenerationStatus, useScrollEntrance
- scripts/: 所有分析脚本 (check-governance, dynamic-analysis 等)

6. 移除未使用的样式文件
----------------------
删除与已移除模块对应的 CSS 文件，保留电商模块专用样式

7. 新增电商模块功能文件
----------------------
+ src/api/generationRecordClient.ts (生成记录客户端)
+ src/features/ecommerce/ecommerceGenerationPersistence.ts (生成持久化)

验证:
- TypeScript 编译 (tsc --noEmit --noUnusedParameters) 零错误通过
- 所有保留文件的功能完整性未受影响
