Empty files (0kb) should be ignored

[StefanOltmann]

Description

It is possible to upload empty (0KB) files either directly or through "watched folders".

Empty files may occur if another application corrupts the files during processing.

To handle these situations, it’s best to skip empty files entirely. Currently, Ente attempts to import such files but cannot generate thumbnails for them.

This behavior can be reproduced easily by creating a new empty text file and renaming it to empty.jpg.

To prevent similar issues, I recommend validating files by checking their magic bytes (see Wikipedia: List of file signatures) before uploading. This helps ensure that files with incorrect extensions don’t enter your system.

For instance, it’s possible to rename any file to photo.jpg and upload it, even if the file isn’t a valid photo (like a ZIP or EXE).
