Allow jquery optional.

Q	A
Is bugfix?	❌
New feature?	✔️
Breaks BC?	❌

This solution implements a way to make jQuery optional, while trying to keep BC as low as possible:

• useJquery property is added to yii\console\Application and yii\web\Application this allows you to control whether jQuery is used or not.
• ActiveForm.
• ActiveField.
• Gridview.
• Validators.
• Add 100% test coverage.

// Application configuration
return [
    'useJquery' => false, // Disable jQuery globally
];

// Or dynamically
Yii::$app->useJquery = false;

// With jQuery default behavior
$form = ActiveForm::begin([]);

// Without jQuery custom client script
$form = ActiveForm::begin(['clientScript' => ActiveFormClientScript::class]);

Two interfaces have been added to add the clientScript to validators, widgets, components, etc.

<?php

declare(strict_types=1);

namespace yii\validators\client;

use yii\base\Model;
use yii\validators\Validator;
use yii\web\View;

interface ClientValidatorScriptInterface
{
    public function getClientOptions(Validator $validator, Model $model, string $attribute): array;
    public function register(Validator $validator, Model $model, string $attribute, View $view): string;
}

<?php


declare(strict_types=1);

namespace yii\web\client;

use yii\base\BaseObject;
use yii\web\View;

interface ClientScriptInterface
{
    public function getClientOptions(BaseObject $object, array $options = []): array;
    public function register(BaseObject $object, View $view, array $options = []): void;
}

Fixed generation of labels, whether custom or not, when enclosedByLabel === false, for both checkbox() and radio().

• Fix checkbox/radio label rendering when enclosedByLabel is false and raise code coverage 100% in ActiveField::class. #20573

To install the assets, i added php-forge/foxy, which i maintain and allows you to install assets easily using the composer installer. i think it would be great to use CDN to manage the assets, so we don't depend on anything external.

Pull Request Overview

This PR introduces the ability to make jQuery optional in Yii2 while maintaining backward compatibility. The implementation adds a useJquery configuration property to applications and refactors widgets and validators to use client script interfaces, allowing for jQuery-free implementations.

Key changes:

• Added useJquery property to web and console applications
• Created client script interfaces for modular validation and widget functionality
• Implemented jQuery-specific client scripts as separate classes
• Moved jQuery-dependent test code to dedicated test files

What's the use for it in console application?

[terabytesoftw]

Because you can use the validators in the console, and JS code will be generated, as in the issue described (#8452), by setting it to false by default, no assets will be registered and no JS code will be generated.
