feat(ui): 文件列表收藏红心 + 首页收藏绑定 favorites 表

Browse Source 
交互调整（按讨论）：
- WebDAV 文件列表：整行点击 = 播放（原来的行为），右侧播放按钮改成收藏红心
  已收藏实心红，未收藏空心；点击即写/删 favorites 表
- 首页"我的收藏"改为读 favorites 表 + songs 元数据；
  从文件列表返回时自动刷新
- 收藏项右侧红心改为真正删除（原来只是内存 removeAt）

修复：
- 收藏列表项透明度绑定 _listReveal，首屏为 0 导致条目完全透明
  （收藏成功但看不到）。收藏项改为固定 opacity 1.0。

验证（真机）：
  列表点红心 -> favorites 表 +1 -> 返回首页 -> 收藏区出现该条目
