Pull request overview

This PR adds chat/messaging provisioning capabilities to the CTI application by integrating with a Matrix-based chat API. The implementation enables Acrobits softphone clients to send and receive messages through the provisioned XML configuration.

Key Changes:

• Added two new helper functions (postJsonRequest and makeCTIRequest) to handle CTI API authentication and requests
• Integrated chat configuration into the account provisioning XML when the CTI API returns Matrix chat endpoints
• Chat functionality gracefully degrades when not available, logging a debug message
