Lot 4 modernisation JS (SonarLint) + restauration CI sonarqube non-bloquante

Corrige les findings SonarQube (via SonarLint IDE, fichier par fichier)
sur ~24 fichiers static/js/ : parseFloat/parseInt -> Number.*,
.replace(/x/g,y) -> .replaceAll, .indexOf() -> .includes()/.startsWith(),
getAttribute/setAttribute -> .dataset, tableaux -> Set, x && x.y -> x?.y
(verifie site par site), extraction de template litteraux imbriques,
ternaires imbriquees, refactors de complexite cognitive (S3776) via
tables de dispatch, Object.hasOwn, .at(), et deduplication de fonctions
identiques (S4144). Deux exceptions S2486 documentees/corrigees
(filter-repeater-rows.js) et un cas S2703 de partage inter-scripts
complete (_collisionWizard, trigger-editor.js <-> collision-rules-editor.js).
Details complets dans CODE_QUALITY.md section 5.

Restaure aussi le job CI "sonarqube" (non-bloquant) dans
.gitea/workflows/deploy.yml maintenant que l'instance prod est
operationnelle.

Suites vertes : 276/276 JS (node --test), 591/591 Python (pytest).

SKIP=djlint sur ce commit : hook djlint bloquant sur le backlog H021
(styles inline, 49 occurrences/6 templates) deja documente comme dette
assumee non traitee dans CODE_QUALITY.md section 6, aucun rapport avec
ce commit (aucun template touche ici) - valide explicitement avec
l'utilisateur avant de contourner ce hook.
