Feature: alarm-panel scale buttons

[boesing]

The request

I am trying to cast a single dashboard to my Google Nest Hub which only contains the hui-alarm-panel-card.
I had a quick view in the source, but the card uses the material design button (which is created in shadow-root) and thus its impossible to change the size of the buttons.

The casted lovelace view looks okayish but I'd prefer having bigger buttons (if configured, not per-default) inside the keypad.

So what I'd like to request is that having an option which resizes the buttons to fill the card entirely instead of just a partial of it. This would make it easier to enter the code via Nest Hub.

The alternatives

None so far. Was trying to modify with card-mod but there is no way to overwrite styling inside a shadow root from the root node.
