feat(tools): enforce stricter rules and add new stylelint plugin

- Added a restriction to prevent circular imports from `features` into `core` modules in ESLint configuration.
- Disabled restricted imports for `features/authentication`.
- Integrated `stylelint-declaration-block-no-ignored-properties` plugin for better CSS validation.
- Updated `package.json` and `package-lock.json` to include the new plugin.
