Build M5 Me & my people for the mobile app

An account-level hub: a header for the signed-in account's own record
(member-since year, a "Team manager {team}" label for someone managing
1-2 teams, otherwise "Staff"), a "People I manage" list linking each
person into M6's edit screen, and a settings card linking into M6 (for
the account's own record) and M7 (Notifications).

The mockup's "Household & contacts"/"Payments & dues" rows and its
"Coach mode" promo have nowhere to lead in this build -- no dedicated
screen for the former, no Coach mode screens at all for the latter (same
precedent base.html's own role switcher already established) -- so
they're omitted rather than built as dead links. "Licence OK" has no
backing field either; each row's meta line uses real current-season
roster data (team + jersey number) instead.
