Boot_Systemd_KPI_Loop: decouple KPI loop from boot transaction

Switch auto-reboot orchestration to a oneshot systemd service + timer.
Let the loop manage iterations/state while keeping the boot path clean.
Ensure the KPI service exits quickly so FinishTimestampMonotonic is not blocked.
Document usage while preserving behavior for manual single-shot runs.
