feat: A1 短材料复现本单元理解词，并加入黑夜模式

Browse Source 
课程内容
- 重写全部 21 个 A1 单元的听读材料，把本单元理解词织进听/读文本，
  单元内理解词复现率从约 20% 提升到约 77%（各单元 56–96%）。
- 修正 U01 房间号与机场大巴同为 thirty 的撞车（改为 17/30/40）。
- 校验器容差按级别读取（A1 为 8%），materials 覆盖率、字数、
  选项子串等校验全部通过；course_content_test 通过。

黑夜模式
- app_theme 拆分明/暗两套调色板，AppColors 随亮度切换；
  main 用 theme/darkTheme/themeMode + builder 镜像已解析亮度；
  主题偏好持久化到快照；进度页新增“外观主题”切换。

文档
- COURSE-PACK-JSON.md 更新 A1 词池覆盖（840/933）与材料复现约定。

"text": "Hi everyone! What are you doing this weekend? There is a big sports event on Saturday. My favorite basketball team has a game, and their best player is excellent. I'm a big fan! We can watch the ball game, and it will be exciting. Do you want to come? On Sunday there is a concert with a band, a singer, a guitar and a piano — a real music activity. Or we can go to the theater for a drama, see some art and paintings, or climb a mountain and camp. Let's choose one and spend the day together. It's fun! Tell me if you'd like to join us.",
