- Created new ArmorSelectionDialog with two tabs:
1. Full Armor Sets: Browse and select complete sets from API
2. Custom Set: Build custom sets from individual pieces
- Armor sets show proper protection and decay per hit
- Decay calculated using official formula: 0.05 * (1 - durability/100000)
- New armor data flows correctly to session cost tracking
- Removed old hardcoded armor set methods
