fix: Remove inline editing toggle on touch devices not to clobber view with unused elements

[fsbraun]

This PR removes the inline editing button on touch devices and in collapsed menus:

• On touch devices inline editing is deactivated not to interfere with scrolling and other touch interactions with the page. The toggle does not have an effect and can be hidden.
• Collapsed menus show the right handside toolbar first since it contains major actions (like "Publish"). No need to take away space for the inline editing toggle here.
