• Add support for auto-detection of trust store types
• Improve error messages for missing or invalid trust store paths
• Add fallback to default trust stores with revocation configuration
• Update ConfiguratorUtilsTest with extended test cases
• Add coverage for invalid anchors, type fallbacks, and precedence behavior

5. Invalid trust store
