Add global site settings view composer with database fallback

Implemented view composer in AppServiceProvider to share site settings across all views:
- Loads site name, logo, colors (primary/secondary/accent), and description from Setting model
- Falls back to config/defaults if database unavailable (prevents errors during migrations)
- Made siteSettings available to all Blade templates

Updated layouts and components to use dynamic settings:
- app.blade.php and guest.blade.php now use siteSettings for

src/app/Providers/AppServiceProvider.php
