Replace the deny-based restriction on granting OWNER with role-scoped
allow policies so authorization fails closed: admins may create and
update memberships only when the assigned role is not OWNER, and the
absence of a target role no longer implies permission.
To keep console UI gating accurate without loosening the base grants,
the permission field gains an optional typed options argument
(PermissionOptionsInput) that forwards target_role into the dry-run
authorization. Only the two role-related console calls (create user,
update membership) pass it; the OWNER option stays hidden for admins via
the existing assignable-roles helper.
Add a non-regression test that an admin cannot promote a member to OWNER
while still being able to change members between non-owner roles.
Move OIDCProviderInfo type into base.graphql alongside its query field
in both connect and trust APIs, removing orphan oidc.graphql files.
Split connect profile.graphql into three domain files: profile (with
user mutations), membership, and invitation.
