fix: scale folder upload timeout by file size (fixes #249)

The folder upload path (uploadFolderEntries) used a flat 10s fetch
timeout for all files regardless of size. Large files like .CR2 RAW
images (~25MB) on slower networks (e.g. Raspberry Pi) exceeded this
timeout, causing the AbortController to kill the request before the
server received the full body — hence no server logs and 'unknown
error' on the frontend.

Changed to size-scaled timeout: 30s base + 2s per MB (min 10s).
A 25MB CR2 now gets ~80s instead of 10s.

 NextCloud was too slow on my home server. So I built OxiCloud — a complete cloud platform written in Rust that runs on minimal hardware and stays out of your way.
