feat(HEL-524): 板块轮动落地 B 五彩版，侧栏/品牌去独立底色

- 新增 5 档强度色 token（日/夜两套，含渐变填充与光晕 alpha），tokens.css
- 板块轮动卡片改为 heat-tier-1..5，固定阈值 <65/65-74/75-84/85-94/95+
  映射青/蓝/紫/橙/红，9 个日期列共用同一套映射，与涨跌无关
- 悬停/选中/追踪三态用 --tier-* 局部变量统一驱动，选中态（当次点击格）
  用渐变实色+2px 亮边+光晕，追踪态（其余同名格）保留档位底色+2px 描边
  +圆点标记，不新增业务状态；修复 hover 规则与 selected 同优先级导致
  悬停会覆盖选中/追踪样式的层叠顺序问题（:hover 增加 :not(.selected)）
- 图例改为 5 档 + “颜色＝强度档位，与涨跌无关” 说明，禁止对普通卡使用绿色
- 侧栏/品牌区去掉独立色块：.module-nav 融入页面 --canvas，
  品牌区与顶栏同层（--header-bg），收起侧栏整行透明；仅作用于
  非移动端且非「问天」路由，问天页面零改动
- 清理死代码：未生效的 .selected 旧规则与引用未定义变量的
  --rotation-heat 声明
- 更新 e2e 断言以匹配新 tier 类名；重新生成 architecture-inventory.json
