powerDownCommands is supposed to run before shutdown, but the current implementation only runs before-sleep, thus not enabling wakeonlan on devices when powering off even if the hardware supports it. Taking into consideration the possibility of unexpected shutdown, it is preferable to move the commands to powerUpCommands instead which is executed at boot time as well as after resume - that should cover all use cases for wakeonlan. Fixes #91352

Interfaces where to enable Wake-On-LAN, and how. Two methods available:
|

"magicpacket" and "password". The password has the shape of six bytes

in hexadecimal separated by a colon each. For more information,
