feat: Allow Layout Edit Button To administrators only - MEED-7509 - M…

…eeds-io/MIPs#147 (#220)

This change will just hide the button of Layout edition from Top Bar, so
that only super administrators will be able to access it. This will
avoid space manager to access this feature by UI until a rework is made
on permissions model to let Platform administrators choose who will be
able to access this feature and button. Besides, improving the
permissions model means that the Portal MOP permission (portal layer)
has to be delegated to SpaceService (social) layer which will be
improved in a dedicated MIP (Space Templates).
