toggle sidebar button unclickable due to OS taskbar behaviour

With a hiding taskbar it's a bit difficult to press the collapse sidebar button, because it's hidden. (Arguably this is a windows and macos issue... but it happens, and annoys me when using headlamp often)

• Move the toggle sidebar controls up about 40px from the bottom

Perhaps we could avoid putting controls at the bottom to work around the issue?

Here's a screen shot of what is seen at the bottom of the headlamp window. (note the collapse sidebar button and kubernetes version buttons are not there)

To reproduce on windows:

• To enable taskbar hiding do: Right click task bar, Taskbar settings -> Taskbar behaviours -> check Automatically hide taskbar.
• Have someone ping you on teams.
• Notice in headlamp you can't collapse the sidebar anymore.
