fix: properly wire cost tracking and loot tracking to new HUD

- Add weapon cost tracking on damage_dealt using session_costs
- Add armor cost tracking on damage_taken using session_costs
- Fix on_loot to use update_kills() and update_loot() with proper params
- Fix on_heal to use update_healing_cost() and on_heal_event() with proper params
- All cost tracking now uses _session_costs from loadout selection
