🌐 Add Portuguese and Dutch language translations

- Introduced `lang/pt` and `lang/nl` directories with translations for `auth.php`, `pagination.php`, `passwords.php`, and `validation.php`.
- Extended existing Spanish (`es.json`) and German (`de.json`) translations with additional keys and values.
- Integrated Laravel Nightwatch package for enhanced language coverage and insights.
- Updated `composer.json` and `composer.lock` to include the new package.
