Neo-Tokyo Neon Noir design pour fiches items

- Nouvelle palette : #080c14 fond, accents néon par type (#00d4d4 item, #ff3d5a kungfu, #4a9eff spell, #cc44ff supernatural)
- Nouveaux composants LESS : .cde-neon-header (clip-path angulaire + accent line), .cde-avatar (clip-path), .cde-stat-grid/.cde-stat-cell (style terminal), .cde-badge (parallélogramme), .cde-neon-tabs (underline néon animé), .cde-check-cell
- Fix layout : .cde-sheet width: 100% + height: 100% + overflow: hidden, .cde-tab-body flex: 1 + min-height: 0, .cde-notes-editor flex stretch
- Fix positions : DEFAULT_OPTIONS height explicite pour tous les types (item 620x580, spell 660x680, kungfu 720x680, supernatural 560x520)
- 4 templates items reécrits avec nouvelles classes et structure épurée
