feat(installer): enable the CPU-mode restore unit

maint-epp-restore.service replays the remembered energy-performance preference
at login, since the kernel resets it to the driver default on every boot. It
hangs off default.target rather than timers.target; systemctl --user can't run
during install, so the enablement symlink is created directly, the same idiom
the scan timers already use.
