    Every question about *which* teams or tryouts belong to this coach is
    delegated to ``app.permissions``. Two of the three methods below used to
    answer it themselves, each considering a different subset of the two
    ways a coach can be attached to a team: ``can_manage_this_tryout``
    ignored the legacy ``coach_id`` column when checking the target team,
    and ``get_visible_tryouts`` ignored it entirely. A coach attached only
    by that column therefore saw an empty calendar (ARCH-002).
