feat(fe): 其余 8 页 + 三个薄组件套用新设计语言

页面：
- record：3×3 emoji 九宫格（184rpx 高、全站最大的点击块）换成图标 + 4 色分类，
  和首页的 8 宫格合并成同一套 .quick-grid，此前它俩是同一个东西的两个副本
- record/plan/community：三套横向切换全部换成 seg-tabs
- record/plan/community/report/learn：砍掉与 nav-bar 重复的 46rpx 大标题，
  每页白赚约 130rpx 首屏
- 时间轴图标改按 HealthRecord.Type 取（9 值枚举，可靠），老数据里的 emoji
  只作兜底；写库的 icon 字段一个字符没动
- profile：设置行加分类图标 + 右侧箭头换图标
- community/report：主操作改深色 CTA，btn-primary 继续留给弹层的「保存」
- 6 套空态写法统一成 .empty

组件：
- nav-bar 的 ‹ 和 fab 的 "AI" 文字换成图标；fab 从蓝渐变改深色，
  和全站唯一主 CTA 的语义对齐
- pet-switch 的「＋」换图标；宠物自己的 emoji 是用户数据，保留

pt-icon 开了 virtualHost，组件标签上的 class 不生效，需要定位的地方
（profile 行图标、箭头）都用外层 view 包了一层。
