Anyone authenticated can still read the shared platform list, but only an
admin may add, rename or delete from it.
- users.is_admin boolean, defaulting to false. The very first account ever
registered becomes an admin automatically (CreateUser's INSERT uses
NOT EXISTS (SELECT 1 FROM users) for is_admin), so there's always at
least one without manual setup; promoting anyone beyond that is a manual
UPDATE for now (documented in the migration's comment on the column).
- GetSessionAndUser, GetUserByEmail and GetUserByID now also select
is_admin, and it flows through to model.User (and so to
/api/auth/{register,login,me}'s response) and to the auth middleware's
authedUser.
- New requireAdminMiddleware + addAdminAuth, layered on top of the existing
auth middleware. Wired onto create/update/delete-platform; list/get stay
on plain addAuth, since reading the list only requires being logged in.
Verified end to end: the first registered user comes back is_admin:true,
the second false; the non-admin gets 403 on create/update/delete-platform
but 200 on list; the admin can do all of it.
