Improve wait_timeout warning messages with detailed connection information

Enhance logging clarity:
- Replace generic IP address with detailed connection info including IP and port
- Use client_myds->addr.addr and client_myds->addr.port for precise identification
- Improve debuggability of timeout clamping and enforcement warnings

The warning messages now provide complete connection details, making it easier
to identify and troubleshoot timeout-related issues in ProxySQL logs.
