make sure the page follows current style guide for navigation

When querying the Groups Project API and including subgroups,
N+1 queries can take place when loading plans for all the groups
in the hierarchy. Plans are only applied at the top-level group
so it is unnecessarily inefficient to load plans for each project
and associated group in the hierarchy. This change loads the plans
once and memoizes them for all project groups.
