Add audit functionality for SingleTask and integrate subject converter and displayer

- Introduced `SingleTaskSubjectConverter` for audit conversion logic and `SingleTaskSubjectDisplayer` for display logic, including a Twig template.
- Integrated `TriggerAuditInterface` into `SingleTaskController` and added audit triggers for create, view, update, delete, and list actions with translatable descriptions.
- Registered new audit-related services in `services.yaml` and loaded `services.yaml` in the extension.
- Created unit tests to validate the behavior of the subject converter and related functionality.
- Added French translations for audit messages related to `SingleTask`.
