Fix: Prevent 'Undefined array key 1' when global Endpoint is requested

When multiple Endpoints are declared, and the frontend requests the global Endpoint (with only one path segment), accessing $segments[1] caused an 'Undefined array key' warning.

This commit adds a count($segments) check to avoid invalid index access and preserve compatibility with global Endpoint logic.
