feat(generate): #1970 智能剪辑流程重构 - 选择模式→素材→标题→确认→封面

## 主流程改造
- STEPS 改为 5 步：选择模式→选择素材→选择标题→确认生成→选择封面
- 原"选择配音"步骤从主流程移除，改为 Step1 下一步分支弹窗
- Step1 新组件 Step1EditMode：模式卡片(🎲随机混剪/📖叙事剪辑，紫底紫框) + 生成设置(数量-/+1-10、比例9:16/16:9、智能降重开关默认开)

## 新增 3 个弹窗
- VoiceSelectModal（随机混剪）：复用配音库音频卡片+▶试听，无 TTS/克隆入口
- ScriptSelectModal（叙事剪辑）：搜索框+300ms防抖+命中黄高亮+标签筛选(全部/带货/工厂/测评/教程/口播/种草)+max-height 420px 卡片列表
- TtsVoiceModal（叙事剪辑合成配音）：Tabs(✨系统音色/🎙️我的克隆音色) + 2列音色卡片 + 合成按钮 + loading(spinner+"正在合成配音..."+"通常10-30秒")

## Step2 素材页
- 叙事剪辑模式显示"🤖 AI智能匹配"紫色提示卡

## Step4 确认页
- 摘要卡片按 editMode 展示剪辑模式+配音来源/文案标题+TTS音色+比例+降重

## payload 新增字段
- assembly_mode('random'|'narrative')、script_id、tts_voice_id、tts_voice_source('preset'|'clone')、dedup_enabled(默认true)、video_ratio('9:16')

## 不改动
- Step3/Step5 内容、文案库/配音库页面、AI数字人
