Rather than hardcoding the icons for all our menu items
let's use the definitions in core.
This also makes it easier for us to deprecate the
MobileMenu hook in future.
Rejoice at all the code this removed!
Bug: T291568

There is still a lot of places that need either an Authority or still
an actual User object. This patch changes the usages that can be
changed right now (almost) without any codechange.
The only additional change is the removal of an unused constructor
argument.
