fix(ui): 奖励卡片被 Framework7 的 .badge 压成灰色小药丸

.badge 在三处定义：Screen.css 的奖励卡、Settings.css 的状态药丸、以及
Framework7 自带的消息计数小圆点。F7 的样式表在打包顺序里排最后，于是
它赢了——每张奖励卡都被强制成 display:inline-flex、固定 20px 高、灰底
白字的圆点，名字和日期硬塞在里面。Screen.css 精心写的卡片样式基本全被
覆盖。65 个奖励堆在一起，看着自然不成样子。

* 奖励卡改名 .award/.award-grid/.award-name/.award-meta/.award-count，
  彻底避开 F7 的全局类名。
* Settings.css 里的 .badge/.badge.ok/.badge.off 没有任何地方引用，是
  死规则，唯一作用就是参与撞车——删掉。
* 顺手让卡片等高、日期用等宽数字对齐、×N 做成右侧小标签。
