Fix kiro credential validation to handle dict-based config

- Updated validate_kiro_credentials() to handle both dict and object config access
- Added get_config_value() helper function for flexible config access
- Now correctly detects kiro-cli credentials from SQLite database
- Validation now works out of the box when kiro-cli is installed
