Add blackbox exporter to monitoring01 to probe TLS endpoints and alert
on expiring certificates. Monitors all ACME-managed certificates from
OpenBao PKI including Caddy auto-TLS services.

Alerts:
- tls_certificate_expiring_soon (< 7 days, warning)
- tls_certificate_expiring_critical (< 24h, critical)
- tls_probe_failed (connectivity issues)
