fix(uploads): avoid file handle leak

[Showmick119]

Fixes #2708

Changes

• Changed except Exception blocks to finally blocks in both sync and async versions of upload_file_chunked
• Ensures file handles are always closed, even on successful uploads

Bug

Previously, file handles were only closed on exceptions, causing resource leaks on successful uploads.

Doesn't using with buf: instead of try/finally look better?

Yes you're correct, with buf: instead of try/finally does look better. Would you like me to make that modification in my PR?

[karpetrosyan]

Yes, please! That'd be great

Thanks!

Agree with Kar, using with would be better but this seems bad so I'd rather merge this fix for now, please file a follow on!
