[DTP-Worker] Sprint 1 · Baseline QA Playwright (4 endpoints) + fix gate rouge

Livrable QA Sprint 1 (roadmap §Sprint 1 · GAP_ANALYSIS §7) : projet Playwright
auto-contenu sous tests/, data-driven sur e2e/routes.json pour /waf-home /crm
/qa /choisir-mon-unite. 4 contrôles/route : status<400 · HTML titré+lang ·
brand luxury (#0a0a12/#f0b429 + Fraunces/Cormorant) · zéro erreur JS/5xx.
Cible via DTP_BASE_URL (aucune URL codée en dur). Zéro invention de chiffres (#6).

- tests/{playwright.config.ts,package.json,tsconfig.json,.gitignore,README.md}
- tests/e2e/{routes.json,smoke.spec.ts,_shared/contract.ts}
- CI : job e2e-baseline manuel (workflow_dispatch) dans .gitea/workflows/ci.yml
  — hors gate push/PR (exige serveur live), Gitea Actions only (#2)
- Fix : gate CI rouge sur HEAD (guard flaguait sa propre doc de test négatif)
  → escape hatch documenté ci-allow. Les 3 scripts du gate repassent verts.
- GAP_ANALYSIS §7 : critère Baseline Playwright → ✅ (exécution VPS différée)
- daily report 2026-07-30 (session 2)
