Ports the Session resource from /api/v1 to the Huma-backed /api/v2 with
list and delete only — sessions are created by the login flow, not CRUD,
so there is no create/read-one/update (and no max_permission or AutoPatch).
The delete path param is a string UUID (path:"session"), not an int64 id,
mapping to the model's string ID. ReadAll is type-asserted to
[]*models.Session; permissions stay at the model level via DoReadAll/DoDelete.
The v2 webtest mirrors v1's session-CRUD matrix (list own vs others',
delete own, non-owner forbidden, nonexistent 404). The login/refresh
auth-flow cases stay on v1.
