Fix orchestrator caller of the renamed user-provisioning command

run_chroot_finalizer still invoked /usr/bin/omarchy-finalize-user, which the
rename moved to omarchy-provision-user — so a normal install died with 'No
such file'. (Deferred-provisioning installs skip this phase, so only normal
installs were affected.)
