refactor: update testing framework and restructure test configurations

- Changed devDependencies from "lua_test" to "testing" in package.json for ui_level4, ui_level5, ui_level6, ui_login, ui_pages, ui_permissions, user_manager, and workflow_editor.
- Removed legacy test scripts and parameterized tests, replacing them with a unified test suite structure in the tests section of package.json.
- Introduced new metadata.params.json files for each package to define test parameters for package ID validation, icon file existence, and JSON schema validation.
- Created new metadata.test.json files for each package to define structured test cases for validating package metadata, including checks for package ID, icon file existence, and schema validity.
