feat: 话题动态化 + 要素化立案 + 知识库增强

话题动态化:
- 新增 POST /topics 端点,AI 根据场景+画像动态生成话题
- 前端3个助手页面改为兜底话题先行,换一批时AI生成
- 去除固化话题列表,支持个性化推荐

要素化立案(对接最高法67类要素表):
- 导入68类要素式起诉状模板到知识库(法〔2025〕82号)
- 覆盖民事/商事/知识产权/行政/刑事自诉/海事/环境/国家赔偿/执行9领域
- ask-analyze 法务场景自动匹配案由模板
- 新增 POST /element-filing 端点,AI填充要素生成要素式起诉状
- ChatPanel 确认事实后可一键生成要素式起诉状,支持复制全文

知识库增强:
- 要素表模板展示全中文化(type/required/标签翻译)
- 知识库页面要素表模板结构化展示(案由/要素清单/诉讼请求)
- 各类型tab显示数量和总数量

画像翻译完善:
- 补充90+个key_facts key中文翻译
- MyProfile多列紧凑布局
