jens 788ddcd0b5 feat: Implement comprehensive architectural guidelines and clean code standards
- Establish feature-based architecture with clear separation between Logic, Data, and Shared layers
- Define directory structure conventions for controllers, entities, DTOs, managers, mappers, models, processors, providers, repositories, and services
- Implement Symfony 7.4+ compliance with proper Request handling (UI layer only)
- Enforce PHP 8+ attributes usage instead of annotations
- Set up proper DTO usage in UseCases with immutable properties
- Configure repository pattern with interfaces in Logic layer and implementations in Data layer
- Implement strict separation of concerns with UI layer handling Request objects exclusively
- Define clear naming conventions (PascalCase for feature names)
- Add shared components directory for reusable elements across features
- Establish HTTP status code constants usage instead of magic numbers
- Configure proper file placement for controllers in UI/Frontend, UI/Api, and UI/CLI subdirectories
- Enforce modern PHP practices with explicit return types and strict typing

This commit lays the foundation for a maintainable, scalable Symfony 7.4+ application following clean architecture principles and modern coding standards.

**/UI/**/*.php, **/Logic/**/DTO/*.php Defines the standard for input validation in Symfony 7 projects. Logic layer DTOs hold the validation rules via attributes. The UI layer is responsible for executing the validation using the injected validator service, ensuring clean separation of concerns and preventing invalid data from entering the business logic. false

All input validation must be performed on DTOs located in /src/Logic/[FeatureName]/DTO using PHP 8 #[Assert...] attributes. Controllers in the UI layer (/src/UI/...) must inject Symfony\Component\Validator\Validator\ValidatorInterface, validate the DTO before passing it to UseCases, and handle validation errors immediately.
