…proper Artisan command and schedule handling

### Issue

With the new fluent configuration API introduced in Laravel 12 for `bootstrap/app.php`, the Console Kernel is not automatically registered in the service container. This causes scheduled commands and Artisan commands to fail silently or report messages like:

> No scheduled commands are ready to run.

and prevents proper execution of Artisan commands.

---

### Solution

This pull request explicitly binds the `Illuminate\Contracts\Console\Kernel` interface to the `App\Console\Kernel` implementation inside `bootstrap/app.php`. This ensures that the framework can correctly resolve the Console Kernel when handling scheduled tasks and Artisan commands.

---

### Changes made

Added the following binding in `bootstrap/app.php`:

```php
use Illuminate\Contracts\Console\Kernel as ConsoleKernelContract;
use App\Console\Kernel as AppConsoleKernel;

$app->singleton(ConsoleKernelContract::class, function ($app) {
    return $app->make(AppConsoleKernel::class);
});
