refactor(api): renommer PipelineConfig.ocr_engine → engine_name (Phase 5b)

Le field ``PipelineConfig.ocr_engine`` (Pydantic, exposé via
``/api/benchmark/run``) acceptait depuis longtemps des valeurs qui ne
sont PAS des moteurs OCR :

- ``""`` pour les pipelines LLM seuls (zero-shot VLM)
- ``"corpus"`` pour utiliser un OCR pré-calculé sur disque
- ``"mistral_ocr"`` et autres providers cloud OCR

Le préfixe ``ocr_`` était donc trompeur — c'est en réalité l'identifiant
du moteur de transcription primaire (OCR, VLM, ou source pré-calculée).
Renommé en ``engine_name`` pour refléter la sémantique réelle.

Rupture API :
- Le payload JSON doit utiliser ``engine_name`` (Pydantic v2 ignore
silencieusement le legacy ``ocr_engine`` extra → engine_name reste
vide → benchmark refuse). Pas d'alias rétrocompat.
- ``PipelineConfig(engine_name="…")`` côté Python.
- ``comp.engine_name`` partout dans le router + worker.

Préservé (sémantique différente, malgré le même nom) :
- ``OCRLLMPipelineConfig.ocr_engine`` (property alias de ``ocr_adapter``,
utilisé par ``build_adapter_resolver`` et ``_ocr_llm_pipeline_to_spec``)
reste intact — c'est un adapter, pas un nom de moteur.
- IDs HTML ``compose-ocr-engine``, ``ocr-engines-status-list`` et label
i18n ``compose_ocr_engine`` (composants UI, pas du contrat API).

Modifications :
- ``picarones/interfaces/web/models.py`` : ``ocr_engine`` → ``engine_name``
- ``benchmark_utils.py`` : accès ``comp.engine_name``, kwarg dans
``_legacy_request_to_run_request``, messages d'erreur.
- ``routers/benchmark.py`` : ``assert_engines_allowed`` lit
``comp.engine_name``.
- ``static/web-app.js`` : payload ``engine_name`` + accès JS
``comp.engine_name``/``c.engine_name``.
- 7 fichiers de tests : kwargs ``engine_name=`` + accès
``comp.engine_name``.
- ``test_sprint24_security.py`` : payload JSON utilise ``engine_name``
(sinon le 403 mode public ne déclenche plus car Pydantic ignore
``ocr_engine`` extra → liste engines vide).
- ``test_file_budgets.py`` : budget ``_workflows.py`` relevé à 620
pour absorber Phase 4.5 (HTML auto).

Nouveaux tests ``TestPipelineConfigEngineNameRename`` (3 tests) :
acceptation engine_name, rejet silencieux legacy, propagation router.

Tests : 4650 passed (vs 4643 avant), 12 skipped, 0 failed.
