fix(ErrorHandler): replace array_first with foreach in isNotFoundException (#644)

On newer stacks (Laravel 12.23+/PHP 8.5 polyfill), global array_first no longer accepts a callback, making isNotFoundException() always true and forcing 404 for all exceptions. Replace with a plain foreach to restore correct detection.
