- Discovery extract/outreach: show '正在分析网站/生成文案' loading message
- Translate: inline '翻译中...' placeholder while waiting
- Marketing: inline 'AI 生成中...' placeholder, success feedback
- Quotations AI: inline progress text + ElMessage.info during generation
- Analytics: add v-loading skeleton with '加载数据分析中...'
- Notifications: add v-loading skeleton with '加载通知中...'
- Followup: wire up '扫描跟进提醒' button with AI progress indicator
