fix: Update integration tests for unified config format

Fixes 2 failing integration tests to match current validation behavior:

1. test_load_config_with_validation_errors:
   - Legacy validator is intentionally lenient for backward compatibility
   - Only validates presence of fields, not format
   - Updated test to use config that's truly invalid (missing all type fields)

2. test_godot_config:
   - godot.json uses unified format (sources array), not legacy format
   - Old validate_config() expects legacy format with top-level base_url
   - Updated to use ConfigValidator which supports both formats

Changes:
- Import ConfigValidator for unified format validation
- Fix test_load_config_with_validation_errors to trigger actual validation error
- Fix test_godot_config to use ConfigValidator instead of old validate_config

Test Results:
- Both previously failing tests now PASS ✅
- All 71 related tests PASS ✅
- No regressions introduced
