Altered & updated permissions repo, and existing connected
RoleController to suit.
Also extracts in-app success notifications to auto activity system.
Tweaked tests where required.
Had misalignment between query and usercan, The nuance between fallback
and entity-role permissions was not taken into account by the query
system. Now added with new test cases to cover.
Ported non-compatible elements, Now all tests passing apart from some
specific permission scenario tests which are probably correctly failing.
Updates some tests to better avoid messing environment state.
