feat: add runtime validation for plugin configurations

- Introduced a new method `validate_plugin_config` in `PluginRuntimeManager` to validate plugin configurations at runtime.
- Implemented the `_normalize_plugin_config` method in `PluginRunner` to normalize and persist plugin configurations.
- Enhanced the `PluginRunner` to handle configuration validation requests and return normalized configurations.
- Updated the WebUI routes to utilize runtime validation for plugin configurations, ensuring that configurations are validated and normalized before saving.
- Added tests for runtime configuration validation and normalization processes, including handling of invalid configurations.
