refactor(backend) : extract CuidEntityTrait, abstract audit subscriber, merge history controllers

- Extract shared ID generation + timestamps into CuidEntityTrait used by all entities
- Create AbstractAuditSubscriber to deduplicate audit logic across 7 subscribers
- Merge per-entity history controllers into single EntityHistoryController
- Delete redundant ComposantHistory/MachineHistory/PieceHistory/ProductHistoryController
- Add OpenApiDecorator for API documentation customization
- Disable failOnDeprecation in PHPUnit (vendor API Platform deprecation)
