Features tab: create/edit flags, flip global switches, and toggle a flag per
club from the club detail page. Where `everyone` is set the per-club toggle is
replaced by a badge, because a toggle there would have no effect and so would
lie about what is on.
Admins tab: grant, promote, demote and revoke platform access. Gated on
is_superuser, not is_staff -- the panel itself is staff-accessible, so letting
staff grant is_superuser would collapse the two levels into one and stop
is_superuser being a boundary we can later hang anything on.
Two guardrails, enforced in the service so they hold regardless of caller:
you cannot strip your own access (you would lose the panel mid-click), and the
last superuser can never be demoted (the platform would be locked out of
itself). Granted users get an unusable password and must enrol 2FA before they
can sign in.
