feat(frontend): 首页信息流与两大核心界面重构

- index.vue: 移除 tabs 单选改为五区块纵向信息流（Hero/排期/歌曲/投稿/消息）
  新增 scrollToSection 平滑滚动与投稿成功自动跳转；为移动端底部导航预留 pb-24
- ScheduleList.vue: 移除左右分栏改为日期横条+时段分组紧凑卡片
  序号采用 28px w900 紫粉蓝渐变 bg-clip-text；卡片三态状态标签色区分
- RequestForm.vue: 序号选择从 pill 升级为 40×40 方格三态（free/taken/selected）
  taken 态删除线+灰色；selected 三色渐变+scale1.05；选中显示「已锁定第N首」提示
