feat: 新增音乐播放模块

- 新增 Music 数据模型 + 迁移（title/subtitle/audioFile）
- 后端：公共 /api/music 查询接口 + 管理端 CRUD
  （音频上传专用 multer，限制 20MB）
- 移动端 /music/:id 播放页：
  - 金色印章式唱片 + 旋转虚线环 + 三重金色涟漪
  - preload=auto + HTTP Range 流式加载
  - 浏览器禁止 autoplay 时显示「轻点聆听」overlay
  - 自定义进度条与时间显示
- Admin：新增音乐管理三页（列表/表单/二维码）与侧栏入口
- 导入示例音乐：朝天宫之歌
- Dockerfile + entrypoint 增加 music 资产回灌
