fix(HRT-81): enregistrer history_bp dans api_v1/__init__.py

- Ajouter import de history_bp depuis .routes.history
- Ajouter app.register_blueprint(history_bp) dans register_api_v1()
- Corriger le docstring du module pour lister /api/v1/history
- Tests: 19/19 passed (GET /api/v1/history — auth, free/premium/pro, validation, pagination)
