Slightly change safety hub expandble toggle

This CL:
- Changes the layout of the safety hub expandable toggle so that
the arrow does not move when the toggle is expanded
- Moves the padding from the text container to the icon container to
avoid double padding for toggles without an icon. The advanced
protection settings uses the toggle without an icon.
