[BUG]: onConstruct Model doesn't work as expected with cached instance of the model

[dz3n]

Describe the bug Not able to initialize property in onConstruct if my model instance is from the cache

Provide minimal script to reproduce the issue

use Phalcon\Events\Manager;
use Phalcon\Mvc\Model;

class Foo extends Model
{
    private Manager $eventManager;

    public $name;

    public function onConstruct()
    {
        $this->eventManager = Di::getDefault()->get('dispatcher')->getEventsManager();
    }
    public function afterUpdate()
    {
        $this->eventManager->fire('foo:updated', $this);
    }
}

$foo =  Foo::findFirst([
    'conditions' => 'id = :id:',
    'bind'       => [
        'id' => 1,
    ],
    'cache' => array(
        'key' => 'key.1',
    )
]);

$foo->name = 'newName';
$foo->update();

//Fatal error: Uncaught Error: Typed property Foo::$eventManager must not be accessed before initialization

Expected behavior Properly triggered event listener afterUpdate

related to https://github.com/phalcon/cphalcon/issues/15837 . unserialize object does not initialize itself in the same way as a normally constructed object (which triggers onConstruct)

i was using onConstruct to trigger

$this->getModelsManager()->keepSnapshots($this, $true);

but this is not happening on unserialize causing issues later on

would implementing the logic in __wakeup be an option?
