style(ui): 全站清除紫色系，统一 Memphis 蜡笔配色

- Logo 渐变从粉紫改为橙/粉/蓝蜡笔色，快门圆点改橙色
- 批量替换 accent：violet→orange、fuchsia→rose、indigo→sky、purple→orange，
  十六进制与 rgb 字面量同步换算为 Tailwind 对应色
- 修复类名合并冲突：管理员筛选 pill 改 fp-orange、会员号改 fp-pink（新增），
  style.css 中去重 fp-rose/fp-orange 并补 fp-pink 的浅色模式变体
- 选区色、标签输入框、筛选 pill、图表、滑块等所有紫色残留全部归位
