[Bug]: The Netdata Dashboard does not scale based on screen resolution

[sashwathn]

Bug description

Some of the Netdata modals do not scale based on screen resolution and makes it difficult for users to select and save preferences.

• The modal after trial ends to select the 5 nodes to visualise - does not show the save button without zooming out
• The modal to invite new users does not show the invite button after the email and the role is selected

These are just a few examples and there are other such modals too.

Expected behavior

All the modals should auto-resize / scale based on the resolution of the screen or allow users to scroll down and finish the action.

Steps to reproduce

1. Open Netdata dashboard on a system with a 12" screen for example
