feat: 审核体系全面改造 — 多维度评分 + 卖点优先级 + AI 语义匹配 + 品牌方 AI 状态通知

后端:
- 审核结果拆分为 4 个独立维度 (法规合规/平台规则/品牌安全/Brief匹配度)
- 卖点优先级从 required:bool 改为三级 (core/recommended/reference)
- AI 语义匹配卖点覆盖 + AI 整体 Brief 匹配度分析
- BriefMatchDetail 评分详情 (覆盖率+亮点+问题点)
- min_selling_points 代理商可配置最少卖点数 + Alembic 迁移
- AI 语境复核过滤误报
- Brief AI 解析 + 规则 AI 解析
- AI 未配置/异常时通知品牌方
- 种子数据更新 (新格式审核结果+brief_match_detail)

前端:
- 三端审核页面展示四维度评分卡片
- 卖点编辑改为三级优先级选择器
- BriefMatchDetail 展示 (覆盖率进度条+亮点+问题)
- min_selling_points 配置 UI
- AI 配置页未配置时静默处理
- 文件预览/下载/签名 URL 优化
