"""t-261018141319: member_remove — безопасное удаление члена (ядро domains/member_ops.py).

Запуск: ./venv/bin/python tests/test_member_remove.py

Сеть/портал НЕ поднимаются: ядро flask-free (sqlite3 + stdlib), тестируется
на временной базе. Проверяет:
- happy-path: users/login_tokens/project_members зачищены, снимок в
  member_archive + json-файл бэкапа (снимок содержит user/shares/votes);
- паи (shares) и голоса (member_votes) НЕ удаляются — финансовая история;
- guardrail: Председателя удалить нельзя (chairman_protected);
- неизвестный id → not_found, без исключения;
- колбэк on_event (MemberRemoved) вызывается с reason/actor;
- файловый бэкап недоступен (dead dir) — удаление всё равно ок (best effort).
