Updated PHP and Few Front Improvements

[voxsar]

This pull request introduces several significant improvements and updates across the codebase, focusing on modernizing dependencies, enhancing exception handling, improving developer tooling, and adding new features for documentation management. Below are the most important changes grouped by theme:

Developer Tooling and Environment:

• Added a GitHub Actions workflow (.github/workflows/php_test.yml) to automate PHP testing with Composer, environment setup, and Pest test execution.
• Replaced the old .php_cs configuration with a comprehensive .php-cs-fixer.php for code style enforcement, adopting more granular and modern rules. [1] [2]
• Updated .env.example with new environment variables (MINIMAL_FRONTEND, SHOULD_EMAIL_EXCEPTIONS, AUTH_REGISTER_ENABLED, HORIZON_TOKEN) and renamed MAIL_DRIVER to MAIL_MAILER for Laravel 8+ compatibility. [1] [2] [3]

Exception Handling and Scheduling:

• Improved exception handling by updating the Handler to use RequestException instead of ClientException, adding current_password to the dontFlash array, and implementing Inertia.js-specific unauthenticated handling. [1] [2] [3]
• Enhanced scheduled tasks: the mail:exceptions command now only runs if should_email_exceptions is enabled in the config, providing more control over email notifications.
• Refactored the RotateExceptions command to directly delete old exceptions, simplifying the logic and improving performance. [1] [2]
• Improved the MailExceptions command to filter users and projects more precisely by notification settings. [1] [2]

Documentation Management Features:

• Introduced a new Filament resource for managing documentation categories, including resource, list, create, and edit pages (DocumentationCategoryResource and related pages). [1] [2] [3] [4]

Dependency and Documentation Updates:

• Updated the minimum PHP version requirement to 8.2 in the README.md and provided new Docker setup instructions for easier local development. [1] [2]
• Cleaned up .babelrc by removing the @babel/plugin-proposal-class-properties plugin, reflecting updated JavaScript standards.

These changes collectively modernize the application stack, streamline development workflows, and introduce new capabilities for documentation management.
