## Bug Fixes - Armor System Serialization

### Issue 1: JSON Serialization Error
**Problem:** "Decimal is not JSON serializable" when saving loadouts with new armor system.

**Root Cause:** The `to_dict` method in `LoadoutConfig` wasn't handling:
- `current_armor_protection` (ProtectionProfile object)
- `current_armor_pieces` (list of ArmorPiece objects)
- `current_armor_decay` (Decimal)

**Fix:** Updated `to_dict` to properly serialize these fields before JSON serialization.

**Commit:** `0c843df`

### Issue 2: Armor Decay Not Loaded Into Session
**Problem:** Warning "Cost tracking not available for file-based loadouts" and armor decay not showing in HUD.

**Root Cause:** 
1. `_get_current_config` wasn't including new armor fields when creating LoadoutConfig
2. `from_dict` wasn't deserializing new armor fields
3. `_set_config` wasn't restoring new armor fields when loading

**Fix:** 
- Updated `_get_current_config` to include new armor fields
- Updated `from_dict` to deserialize `current_armor_protection`, `current_armor_pieces`, `current_armor_decay`
- Updated `_set_config` to restore new armor fields
- Updated `_on_loadout_selected_for_session` to extract cost data for JSON-based loadouts

**Commit:** `8308425`

## Technical Details

### Files Modified
- `ui/loadout_manager.py` - Serialization/deserialization fixes
- `ui/main_window.py` - Cost extraction for session start

### Key Changes
1. `to_dict` now handles complex objects manually instead of using `asdict()` blindly
2. `from_dict` converts Decimals and reconstructs ProtectionProfile/ArmorPiece objects
3. Session startup now extracts costs from both database and JSON loadouts

## Testing Status
- JSON serialization fixed
- Armor decay now flows from LoadoutManager → JSON file → Session
- Need to verify live cost tracking in HUD during gameplay
