fix(template): 修复 5 处 :style 内未加引号的 hex 表达式

- mbti-test / psych-assessment：进度条 :style 里的 background: #xxxxxx 属非法 JS 表达式
  （模板编译会报 Invalid expression），改为背景色进 class（\-wisdom / \-wealth），
  内联只留动态 width
- message-history：3 处 :style='{ color: x >= 0 ? #10B981 : #EF4444 }' 改为
  :class 切换 amount-pos / amount-neg（\-success / \-danger）
- 全站模板表达式 hex 违规清零（剩余 prop=#hex 属小程序组件属性色值，编译期不可达 SCSS，
  按计划边界保留）
- 3 文件 node --check + dart-sass 编译通过；硬编码色 493 -> 485
