refactor(glass): 使用 GlassMediaServiceHelper 替换直接的 GlassSdk 调用

- 在 SprayingActivity 中使用 GlassMediaServiceHelper.takePhoto 替换 GlassSdk.getGlassMediaService().takePhoto
- 在 SprayingActivity 中使用 GlassMediaServiceHelper.addPhotoCallback 和 removePhotoCallback
- 在 SprayingOCRActivity 中实现相同的 GlassMediaServiceHelper 替换
- 在 SprayingResultActivity 中实现相同的 GlassMediaServiceHelper 替换
- 为 SprayingFinishActivity 和 SprayingOCRActivity 添加图片资源清理
- 在 SprayingResultActivity 的 submit 操作后启动 TaskListActivity
- 创建 GlassMediaServiceHelper 单例类封装媒体服务操作
