Anton Afanasyeu 46a7592164 monitoring: fix false HttpEndpointDown alert for self-signed FE cert
- blackbox.yml: add http_2xx_insecure module (TLS skip) for FE probing
- prometheus.yml: split blackbox_http (internal HTTP) vs blackbox_https_external
  (external HTTPS targets using insecure module); remove notify.f0xx.org probe
  until FE nginx proxies it
- service_alerts.yml: HttpEndpointDown/SlowResponse cover both jobs via regex
- TODO: replace http_2xx_insecure with strict module once FE gets LE cert
