fix(teaching-schedule): 当日课表展示所有状态，并支持点入课程详情

- 后端 getTeachingScheduleByDate 在查询当天时不再以 PENDING/CONFIRMED 过滤 timeSlot
  也不限制 include.bookings 的状态，但仍保留 EXISTS 守卫过滤空 slot
- 其他日期维持原「只看待上课」语义
- 抽出私有 formatLocalDate 工具方法，消除服务端 YYYY-MM-DD 构造的 3 处重复
- 前端 teaching-schedule 的 session 卡片可点击跳到 /pages/booking/detail?slotId=
- 补全 student__status--completed / --cancelled 样式
