Move inline styles to global CSS file

Moved .log-highlight styles from Livewire component views to resources/css/app.css for better separation of concerns and reusability. This follows Laravel and Livewire best practices by keeping styles in the appropriate location rather than inline in component views.

Changes:
- Added .log-highlight styles to resources/css/app.css
- Removed inline <style> tags from deployment/show.blade.php
- Removed inline <style> tags from get-logs.blade.php
- Added XSS security test for log viewer
- Applied code formatting with Laravel Pint
