Subject: [PATCH] fix: only send library association on create when libraryIds
 is defined

Guard the createUser library association call with
libraryIds !== undefined, matching the updateUser pattern. This prevents
accidentally clearing backend default library assignments when the form
field hasn't been initialized yet.
