Power the printer (mainboard) off and on

[Sonnenwerk]

Is your feature request related to a problem? Please describe

If i want to change port of fans and other devices on my printers mainboard, i have to power down my whole printer, including my host and all connected stuff. Rebooting it is a time sink.

I changed my hardware, so that i can powerdown/powerup my mainboard via a shelly seperatly. Now i would like not to use the shelly cloud, but issue the off/on commands via the printerweb ui. I learned, that for this i can use moonraker.

Describe the solution you'd like

I figuered out (hopefully correct) how to write the config in moonraker. But i found no Button for it in Fluidd.
I found out, that mainsail already had such an implementation and would like to request such a feature also for fluidd.

Describe alternatives you've considered

mainsail-crew/mainsail#897 --> the request in the mainsail git
and https://docs.mainsail.xyz/overview/quicktips/printer-power-switch as other alternative. I don´t know how mainsail did it finally.
--> add:
#1350 -> already a FR for a Powerbutton change (but a little bit different)
