Featureflip Organizations API
The caller's organizations. `List` has no `{org}` segment (pass-through tenant filter) and dispatches ListOrganizationsQuery, which already scopes to the caller's own memberships. `Get` carries `{org}`, so ResolveTenantFilter resolves + access-checks it first — the action dispatches GetOrganizationQuery with the resolved GUID (ResolvedOrgId), never the raw route string.
