Génération PDF asynchrone : jobs avec polling + progression

- Nouveau système de jobs : POST /jobs (async), GET /jobs/{id} (status), GET /jobs/{id}/result (PDF), DELETE /jobs/{id}
- worker.php spawné en arrière-plan via nohup, lit la sortie pagedjs-cli ligne par ligne via proc_open et écrit la progression dans tmp/job_{id}.status.json
- Migration de pagedjs-cli en install local (node_modules) pour persister le patch protocolTimeout via patch-package
- CI : déploie package.json, worker.php, patches/, et lance npm install (qui réapplique les patches via postinstall)
