The /file-entries/duplicate endpoint returns a 500 Server Error for
every request (reported to Drime 2026-06) which made all server side
copies fail after 10 retries. Remove the Copy method so rclone falls
back to downloading and re-uploading instead. It can be restored if
Drime fix the endpoint.
The server stores the SMB last write time with 100 ns (FILETIME)
precision and returns it in full in listings, so advertise that as
the precision instead of one second. This makes syncs preserve
sub-second modtimes when comparing and copying files.
Note that this means rclone will consider files with modtimes
differing by less than a second as needing their modtime set where
before it did not.
