refactor(common-config): extract snippet from editor content instead of active provider

- Change extraction source from current active provider to editor's live content
- Add i18n support for JSON parse error messages via invalid_json_format_error()
- Simplify API by removing unused providerId parameter
- Update button labels and error messages in zh/en/ja locales
