fix(fail2ban): treat process as active when client ping succeeds (#13679)

Browse Source 
Fail2ban UI currently keys isActive only on systemd fail2ban.service.
If the daemon is alive under another process manager, whitelist and
blacklist stay disabled. Detect liveness with fail2ban-client ping.

Fixes #13678
