Add a ``TransactionCase`` test suite covering the module behaviour: - ``_define_user_id`` decision rules (no team, no current user, user not in team, user in team, team without leader). - ``create`` auto-assignment (with/without partner, with/without default team, explicit team not overridden, partner without linked user, batch ``vals_list`` creation). - ``_compute_user_id`` recomputation on team change. - Full portal creation flow (team + project + user) and presence of the ``default_helpdesk_ticket_team_id`` field on ``res.users``.
