Fix WhatsApp Business API tool conflict

A WhatsApp Business number is stuck in a broken integration state that is blocking further development. The number was previously connected to ManyChat and was successfully deactivated and deleted from that platform. However, when attempting to connect a different third-party tool to the same WhatsApp Business number via the Meta platform, the process fails with an error stating that an existing tool is already connected to that number — even though ManyChat has been removed. The owner has developer-level experience and has independently tried multiple approaches to resolve this, all without success. The issue appears to be a lingering association on Meta's side between the WhatsApp Business number and the old integration, preventing any new tool from being linked. The ideal candidate has hands-on experience working with Meta Business Suite, WhatsApp Business API, and the Meta developer ecosystem. They should be comfortable navigating Meta's backend, Business Manager settings, and WABA (WhatsApp Business Account) configurations to identify and clear the stale connection so that a new third-party tool can be successfully connected to the number. somthing like chatbot problem
