Large files (sent as multipart uploads) were placed in the wrong folder
for two reasons:
- the parent folder was sent as "parent_id", but the API ignores that
and expects "parentId", so the parent was never honoured
- relativePath was sent as the full path from the drive root, which made
the server build folders from it and silently drop any "0" path
segment (e.g. ".../data/0/file" lost the "0")
Send the parent as "parentId" and use just the leaf as relativePath,
matching the working single-part upload. This also lets us remove the
now-unneeded absolute-path resolution code.
