Harry 3f5f893e6c feat: add exists method to sandbox sources for existence checks
- Implemented the `exists` method in `SandboxFileSource` and its subclasses to verify the availability of sandbox sources.
- Updated `SandboxFileService` to utilize the new `exists` method for improved error handling when listing files and downloading files.
- Removed the previous check for storage existence in `archive_source.py` and replaced it with the new method.
