Fix Shelly unreachable: roll back engine state on failed actions

Browse Source 
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.
