Subject: [PATCH] fix: prepend folder prefix to filename before upload so AMPP
 can sort by folder

Restore the original working approach: build the prefixed filename
(e.g. Media--Dailies--clip.mxf) client-side before sending to any
upload endpoint, and pass prefix:'' to the server.

Changed in uploadFilePresigned() and uploadFileViaServer():
- Compute prefixedName from selectedPrefix with slashes converted to --
- Pass filename: prefixedName, prefix: '' to all three upload paths
  (/api/presigned, /api/desktop/multipart/init, /api/upload formData)
