Replace value with canonical in PersonIdentifier unique constraint, repository logic, and tests

- 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.
