refactor(pricing): refonte v7.0 — 3 Cloud (Basic 189$/Essentiel 349$/Pro 549$) + DictIA Local (5998$ An1) + Pro+ soumission

Remplace l'ancien pricing (DictIA 8 / 16 / Cloud) par la nouvelle structure
canonique v7.0 : 4 forfaits + 1 sentinel quote-only.

Changements clés :
- pricing_card.html : signature étendue (badge, recommended, capacity_audio,
  capacity_storage, gpu, yearly_renewal, cta_label) + format prix server-side
  avec NBSP OQLF (5998 -> 5 998 $)
- _pricing_tiers.html : 4 cards (Cloud Basic 189$, Cloud Essentiel 349$,
  Cloud Pro 549$+485$ RECOMMANDÉ, DictIA Local 5998$ An1) + chip Pro+
  soumission -> /contact?pro-plus=1
- plans.py : refonte complète avec yearly_renewal_env (DictIA Local An 2+ =
  500$/an) + is_quote_only sentinel (Pro+ -> redirect /contact, jamais Stripe)
- routes.py : Pro+ intercepté avant le flow Stripe Checkout
- env.stripe.example : nouveau naming STRIPE_CLOUD_BASIC|ESSENTIEL|PRO_*
  + STRIPE_DICTIA_LOCAL_SETUP/RENEWAL_YEARLY
- tarifs.html : header "Quatre forfaits", matrice comparative 4 colonnes,
  FAQ enrichie (7 questions incluant DictIA Local + onboarding Pro + Pro+)
- fonctionnalites.html : section Architecture refondue (4 cards v7.0)
- landing.html : ROI footnote + cycle "189$" + wave "189$/mois" actualisés
- roi_calculator.js : recalibrage sur Cloud ESSENTIEL 349$ × 12 = 4188$/an
- routes.py marketing : FAQ "DictIA 8 et 16" -> "DictIA LOCAL"
- contact.html : "déploiements DictIA 16" -> "Cloud PRO" + "DictIA LOCAL"

Tests :
- test_marketing_landing_template.py : assertions prix v7.0 (189/349/549/5998),
  4 slugs (cloud-basic, cloud-essentiel, cloud-pro, dictia-local), Pro+ chip,
  capacity chips, RECOMMANDÉ sur Cloud PRO
- test_marketing_secondary_pages.py : 4 cards + Pro+ chip + matrice 4 col +
  FAQ 7 questions
- test_stripe_checkout.py : env vars v7.0, slugs cloud-basic/cloud-pro/
  dictia-local + nouveau test pro-plus -> /contact + tests setup pour Cloud PRO
  et DictIA Local
- test_stripe_webhook.py : plan_slug metadata cloud-basic

Status : 28/28 Stripe checkout + 17/17 webhook + 93/98 marketing pass
(les 5 marketing failures sont pré-existantes, non liées au pricing :
test_landing_has_main_nav et test_footer_links_complete = /blog manquant ;
test_trust_bar_has_eyebrow_factual_phrasing + 2 tests conformite =
