chore(infra): synchroniser l'infrastructure depuis le TP de référence

Mise à jour automatique des fichiers d'infrastructure (workflows
GitHub Actions, autograding, devcontainer, configs IDE, helpers,
README, pom.xml) et des éventuels dossiers de référence sous src/
déclarés pour ce TP. L'espace de travail étudiant (le reste de src/)
n'est jamais touché.

Propagé par le workflow sync-students.yml du repo
IUTInfoAix-R203/classroom-sync.
