Lutz Finsterle	f45d23df97	Fix Shelly unreachable: roll back engine state on failed actions ... Without this, a failed Execute() left engine state diverged from hardware. SyncHardwareState would then misread the mismatch as a manual override and apply a 1-hour lockout — causing either a stuck-on or stuck-off loop. Now Execute() returns per-action []error. The control loop calls Engine.RollbackAction() for each failed action, keeping engine state in sync with hardware so the next cycle simply retries.
