feat(pricing): recalibrate to real Hytale market (149€/349€/790€)

Pricing refonte après rapport 3 (RESEARCH/Hytale/3 Pricing Calibration).

**Décision clé du rapport** : aucun serveur Hytale n'a payé €500+ pour
un plugin single en 2026 (public data). Top server Runeteria = 29 CCU
peak, €200-800/mois gross revenue ceiling. 70-80% du top 30 serveurs
= volunteer/owner-coded, zéro budget externe.

**Nouvelle grille adaptée à la réalité du marché Hytale** :
- Plugin Essentiel     149€   (1 feature, ≤8h, livraison 3-5j)
- Système Sur-Mesure   349€   (GUI in-game, ≤20h, 1-2 sem)  [featured]
- Module Flagship      790€   (quote-based, top-30 tier only)
- Retainer Mensuel     450€/mois (~12h/mo)
- Site Gaming          500€

**Ajout** : pricingNote avec mention 45€/h (spot fixes) et flagship CTA.

Ancienne grille (400€/1500€/5000€) filtrait 95% du marché — non viable.
Nouvelle grille capture ~85% de la demande Hytale observée tout en
laissant room upsell pour les 5-8 flagship servers réels.

RESEARCH/Hytale/3 ajouté (rapport complet avec top 30 audit, BBB
scatter analysis, WTP evidence par segment, 3 scénarios projetés).
