feat: gestion de la Fiabilité du matériel (test de Fiabilité + réparations)

- module/system/reliability.mjs : VermineReliability
  - Test de Fiabilité : jet Xd10 (Mineurs 1D / Graves 3D / Critiques 5D),
    chaque dé >= Fiabilité inflige 1 Dommage ; réduit Fiabilité et dommages
    cumulés (panne/état/effet) ; destruction à 0
  - Traits appliqués : Coque (absorbe n puis se perd), Cassant (+1 perte),
    Étanche (Dommages d'immersion ignorés si Fiabilité au max)
  - Réparations : classique (Précision + Artisanat/Mécanique/Technologie/
    Armurerie vs Fiabilité d'origine + Handicap de panne, +1 Fiabilité/Réussite)
    et de fortune (Précision + Bricolage, panne réparée sans gain de Fiabilité)
- ReliabilityDialog (test/réparation) + cartes de chat dédiées
- Boutons Test de Fiabilité / Réparer sur les fiches d'items (weapon/defense/item)
- i18n fr/en + styles des cartes et boutons
