test: A32 phase 2b — api.py 3 → 16/22 routes couvertes (v7.13.0)

+6 smokes dans test_smoke_uncovered.py (22 tests au total dans le fichier) :
- board-config GET/POST : défauts 5 colonnes sans board, création puis
  relecture du roundtrip (seed via l'endpoint lui-même, pas de SQL brut)
- col-mapping POST/DELETE : 404 sans board, upsert label vérifié, suppression
- card POST : 404 sans board, ok avec
- collaborators GET : gitea.get_collaborators STUBBÉ (zéro accès réseau réel)
- frontend-error(s) : capture, JSON invalide → ignored, DÉDUP d'une erreur
  répétée (count=2), lecture qui purge (cleared=true puis 0)
- checklist mutations : PATCH item (checked/content relus EN BASE), DELETE
  item, DELETE checklist (COUNT=0) — seed + cleanup en finally

Reste api.py : 6 routes Gitea (issues ×4 + créations checklists owner/repo) →
stub de transport httpx (phase suivante). Reste global : dashboard 17/63,
api_v2 50/115.
