[Renaud Hager (renaudhager)]

This pull request adds new documentation and updates existing docs for Shopware PaaS Native, focusing on Fastly CDN configuration, security features, and PHP settings. The changes introduce dedicated pages for Fastly snippet management and security features (WAF), clarify Fastly service configuration, and provide improved guidance for PHP configuration in the application YAML and environment variables.

Fastly CDN and Security Documentation:

• Added a new page detailing Fastly snippet configuration for the storefront service, including installation instructions and current limitations.
• Introduced a new security features page describing the default Web Application Firewall (WAF) powered by Fastly NGWAF, with notes on future enhancements.
• Updated the main Fastly CDN documentation to reference the new snippet configuration page and clarified the distinction between the storefront and cdn Fastly services.

PHP Configuration Documentation:

• Added a new page for PHP settings configuration, documenting environment variables that control PHP behavior and linking to the official Shopware Docker image.
• Enhanced the application YAML documentation to show how to specify PHP extensions, including examples and a description of the installer used. [1] [2] [3]
