fix(frontend): U7 返工 - 大字号/字重收口核验 FAIL 修复（5 项必修）

按独立核验报告 verify-u7-fontsize-fontweight.md 逐项落实：
1. uni.scss 删除 6xl 后定义重复块（100rpx 覆盖 96rpx），-font-size-6xl 实际生效 96rpx
2. 回滚 24 处 48rpx→4xl(64rpx) 错映射为 -font-size-display(48rpx)，与拍板「48 保真」一致
3. 回滚 9 处 80rpx→6xl(100rpx) 错映射为 -font-size-5xl(80rpx)
4. 落实拍板②：9 处 font-weight:300 → 400
5. MemberSelector.vue 恢复 .empty-icon/.empty-title 两条规则分行格式

仅改 cfc-frontend/ 样式（font-size/font-weight 值 + uni.scss 令牌），不动模板/脚本/逻辑/路由/DB。
保留 calc(NNrpx * var(--font-scale, 1)) 包裹形态；不改 custom-tab-bar/index.vue。
