[Synology] Synology Photos iOS 2.0.0 大更新

使用體驗總算跟上 Google Photos 的腳步了，能在 Photos 裡面看到本機的照片，本地修改照片也會重新上傳，刪除照片也會同步刪除本地照片，算是能當做本地相冊在用了。

What's New:

1. Supports viewing all photos, regardless of whether they are backed up or not, in the mobile app after backup is enabled.
2. Supports backing up modified photos again to keep all changes after backup is enabled.
3. Supports deleting photos stored on both your phone and Synology NAS at the same time.
4. Supports backing up and uploading multiple files at the same time for better efficiency.

Fixed Issues:

1. Fixed an issue where leaving lightbox mode before the download completes might not be successful.
2. Fixed an issue where the limit of the cache size might be exceeded.
