test: Configure Celery for integration tests and setup Redis

- Add Celery synchronous execution settings for tests
  * CELERY_TASK_ALWAYS_EAGER = True (no separate worker needed)
  * CELERY_TASK_EAGER_PROPAGATES = True
  * Use memory broker/backend for tests

- Add performance marker to pytest.ini
  * Allows marking tests with @pytest.mark.performance

- Setup Redis server via systemd
  * Enabled redis-server.service for autostart
  * Redis runs on 127.0.0.1:6379

- Update .gitignore to exclude dump.rdb (Redis dump file)

Integration tests status:
- 26/47 tests passing (55%)
- 21 tests failing due to missing NotificationType fixtures
- Tests no longer hang (Celery executes synchronously)

Note: Integration tests require NotificationType fixtures to be created
before document operations trigger notification signals.
