Add audit functionality for Activity actions

- Introduced `ActivityDisplayer` and `ActivitySubjectConverter` for handling audit display and conversion logic.
- Integrated `TriggerAuditInterface` in `ActivityController` and added audit triggers for create, list, update, delete, and view actions with translatable descriptions.
- Updated `services.yaml` to register new audit-related services.
- Enhanced French translations with audit-related labels for `Activity`.
