- Replaced `Person` entity binding with `PersonCreateDTO` in `CreationPersonType` to enable better data handling.
- Added `PersonCreateDTOFactory` for creating and mapping `PersonCreateDTO` instances.
- Extracted `newAction` logic into `PersonCreateController` for clearer separation of responsibilities.
- Updated `PersonIdentifiersDataMapper` and `PersonIdentifierWorker` to support default identifier values.
- Adjusted related services, configurations, and templates accordingly.
- Implemented `validate` method in `StringIdentifier` to enforce `only_numbers` and `fixed_length` constraints.
- Created `StringIdentifierValidationTest` to cover validation rules.
- Update unique constraint on `PersonIdentifier` to use `canonical` instead of `value`.
- Refactor repository method `findByDefinitionAndValue` to `findByDefinitionAndCanonical`, updating logic accordingly.
- Adjust validation logic in `UniqueIdentifierConstraintValidator` to align with the new canonical-based approach.
- Modify related integration and unit tests to support the changes.
- Inject `PersonIdentifierManagerInterface` into the repository to handle canonical value generation.
