feat: add fallback mechanism when fs.rename is unsupported

[OpenSrcerer]

📝 Description

FUSE filesystems don't seem to play nice with the fs.rename(..) calls. When I try to upload any file, even if I put both the temp-uploads and uploads dirs to live inside the same FUSE fs, this was the result:

palmr  | Error in filesystem upload: Error: EXDEV: cross-device link not permitted, rename '/app/server/temp-uploads/1759071669706-nhwtia-cmg3q5e3y0000my097faemen9/1759071669672-fGolBOeeC41E.mp3.tmp' -> '/app/server/uploads/cmg3q5e3y0000my097faemen9/1759071669672-fGolBOeeC41E.mp3'

palmr  |   path: '/app/server/temp-uploads/1759071669706-nhwtia-cmg3q5e3y0000my097faemen9/1759071669672-fGolBOeeC41E.mp3.tmp',

palmr  | }

So, I've added a wrapper that reverts back to fs.copy(..) + fs.unlink(..) when such an error is detected.

💡 Motivation and Context

I don't have plenty of storage on my device, but I do have plenty in the cloud. Thus, taking inspiration from network drives, I mounted a Google Drive folder to use as my storage medium for Palmr, which is what I was using to reproduce the issue. I believe that this is a clean way to implement storage.
