Fix toggleSidebar ID and add to default toolbar

Fixes the ID of the sidebar from `toggleSidebar` to the correct `sidebarToggle`

Adds the sidebarToggle button to the default toolbar.
This should not affect existing users, unless they drag the default toolbar
but *should* affect new users.

Replaces: Ranchero-Software#4242
Closes: Ranchero-Software#4103
