profile: render profile on desktop via QtQuick

Browse source 
This breaks all dynamic features, including animations,
zooming tooltips, planner-handles, etc. They will have to be
converted one-by-one to QtQuick, which will be a major pain,
as the ProfileView is destroyed by Qt6 on reparenting.
This means that the view cannot store any persistent state.
