Fix: getDoctrineSchemaManager compatibility with Laravel 11 and Doctrine DBAL 3+

[IlhamriSKY]

This PR addresses a compatibility issue when using Laravel 11.x with the orangehill/iseed package.

In Laravel 11, calling getDoctrineSchemaManager() on a database connection throws the following error:

BadMethodCallException: Method Illuminate\Database\MySqlConnection::getDoctrineSchemaManager does not exist.

Even after installing doctrine/dbal, the method is not exposed unless accessed via a Doctrine connection manually. Additionally, $this->databaseName can be null, which causes:

Trying to access array offset on null

…when fetching connection configuration.

✅ Solution

• Fallback to Laravel's default database connection when $this->databaseName is null.
• Use Doctrine DBAL directly via DriverManager::getConnection() and createSchemaManager() to ensure compatibility with Laravel 11 and DBAL v3.

✅ Tested on:

• Laravel 11.44.2
• Doctrine DBAL ^3.6
