After deactivation the endpoint now calls _run_probe to flush the
cached server status immediately, matching the activate_jail behaviour
added in Task 5. Without this, the dashboard active-jail count could
remain stale for up to 30 s after a deactivation reload.
- config.py: capture result, await _run_probe, return result
- test_config.py: add test_deactivate_triggers_health_probe; fix 3
pre-existing UP017 ruff warnings (datetime.UTC alias)
- test_health.py: update test to assert the new fail2ban field
