SAUTECH MONITORING - CORRECT PRODUCTION LAYOUT

Web application:
  https://apps.sautech.net/monitoring/

Deploy everything INSIDE the monitoring/ folder to the web root folder:
  .../apps.sautech.net/monitoring/

Agent API:
  https://apps.sautech.net/monitoring/agent_api.php

WhatsApp remains a SEPARATE sibling folder:
  https://apps.sautech.net/whatsapp/

Meta callback MUST remain:
  https://apps.sautech.net/whatsapp/webhook.php

Deploy:
  whatsapp/webhook.php
to the existing /whatsapp folder.

The webhook loads:
  ../monitoring/lib.php
so incoming WhatsApp messages and Meta delivery/read statuses are stored in the
same monitor.db used by the combined monitoring portal.

Do NOT move the webhook under /monitoring.
Do NOT change Meta's callback URL to /monitoring.

The combined monitoring portal's "WhatsApp Replies" page reads those stored messages
and allows admin to reply, remove from inbox, restore, and keep history.

Agents included under monitoring/agents are configured to:
  https://apps.sautech.net/monitoring/agent_api.php

The separate future uptime/checkpoint area mentioned previously is NOT used as a
WhatsApp webhook path.
