fix: web GUI upload Content-Type mismatch with presigned URL

Browse source 
Same fix as the Chrome extension — the web GUI's uploadHTTP() was using
item.file.type (browser-determined MIME) instead of presigned.contentType
(server-signed MIME). For broadcast formats like MXF, R3D, BRAW where
the browser returns empty or generic types, this causes an S3 signature
mismatch and the PUT fails.
