More iframe customisation

Description

Hi
I absolutely love homarr, but one thing I think is missing, is more customisation on the iframes, iframes are just such a big topic.

For example having the possiblity to set custom html code, like overflow: hidden, scrolling=no, for example hide the

of the iframed webpage etc.
as a example I use the https://galaxus.ch/en/daily-deal page as iframe to see their daily offer, but the header object is absolutely enourmous, and I'd love to be able to remove it.

(There is a extensions, like this neccessary to overcome this specific website: https://github.com/ThomazPom/Moz-Ext-Ignore-X-Frame-Options)

Thanks!
