Simulated Failed Logins Appear As Ban Records
    [Documentation]    Verifies the full ban pipeline:
    ...    fail2ban log parsing → fail2ban ban → backend socket poll → UI rendering.
    ...
    ...    Key timing facts:
    ...    - simulate_failed_logins.sh writes 5 lines (COUNT=5).
    ...    - manual-Jail maxretry=3 → ban triggers after 3rd matching line.
    ...    - fail2ban backend=polling → fail2ban re-reads auth.log on its own schedule.
    ...    - Backend has no push mechanism; /api/bans/active queries fail2ban on demand.
    ...    - history_sync runs every 300 s; history page reads from the archive DB.
    ...    - A direct API assertion (Step 3) isolates backend from UI rendering issues.

    # Step 2 — wait for fail2ban to process the ban
    # polling backend; no fixed interval but the ban is near-instant once detected.

    # Step 3 — backend API: confirm ban via Python in fail2ban container.
    # Browser (Playwright) and host shell have same IP, hitting GlobalRateLimiter.
    # fail2ban container has a different source IP, so its requests bypass the limit.
    # Container reaches backend via host network (localhost:8000).
