Limit max length integration panel on Mobile

[Mariusthvdb]

When using integrations with a lot of config entries (think Shelly switches, Here travel time, or Mobile app) that listing on /config/integrations is limited by the integration pane size on Desktop (and it can be even too small to be really practical, but at least we can scroll.

On a mobile device this is not the case, and the list is just as long as there are entries. Currently I have one that holds over 100(...) which is ok-ish on desktop:

and scrolling past that Integration on mobile is a terrible UX.

Please consider limiting the max list length of those panes, and allow scrolling per integration pane if over a certain length.
