Add integrator and child account support

[gogl92]

1️⃣ This PR introduces full support for PrintNode Integrator accounts, fulfilling a direct user request for managing child accounts.

2️⃣ All changes are cohesive and directly related to the implementation of Integrator account functionality.

3️⃣ Yes, comprehensive unit and feature tests have been added for the AccountService, Account entity, and AccountRequest builder.

4️⃣ This improvement adds robust support for PrintNode Integrator accounts, enabling developers to programmatically manage child accounts. This is crucial for multi-tenant applications (e.g., SaaS platforms) that need to provide isolated printing capabilities to their customers.

Key features include:

• Child Account Management: Create, retrieve, update, suspend, activate, and delete child accounts.
• API Key & Tag Management: Generate and manage API keys, and associate custom tags with child accounts for metadata.
• "Act on Behalf" Functionality: Perform API operations (e.g., managing printers, submitting print jobs) as if you were the child account, using X-Child-Account-By-Id or X-Child-Account-By-CreatorRef headers.
• Statistics & Data Download: Access detailed statistics and download all data for child accounts.

This functionality allows for a more secure, scalable, and automated way to integrate PrintNode into complex applications, centralizing control while maintaining customer data separation. Extensive documentation has also been added to guide usage.

5️⃣ Thanks for contributing! 🙌
