Laravel skeleton project

This skeleton includes:

• All classes marked as final.
• All PHP files marked with declare(strict_types=1);.
• Reduced dependency count (I don't need Sanctum, Pint, etc. I'll install them when they will required).
• Added static analysis tool - Psalm with max strict level as possible (1). My code should be clean and strong as possible.
• Added code style checker and beautifier.
• Added Github Actions for checking code style, running static analysis and tests.
• Project code located in src folder and base files have different from default namespaces.
• Useless comments were removed.
• Useless doc-blocks were removed and replaced with type hints when it's possible.
• Removed Facade and helper usages. I think Service Locator is an anti-pattern and prefer to use Dependency Injection.
• Removed built-in model factories. I prefer to use my own factory implementation outside of models. Models have too many responsibilities and removing at least factories from them looks a little bit better.
• Removed broadcast service provider and routes. It can be added when it will be required.
• Removed console routes. I prefer to use Command classes.
• Removed api & web route files. As it shows in practice, I don't use them every time when I'm creating new Laravel project and prefer to locate them in another places within their Service Providers like a DashboardServiceProvider.php, dashboard_routes.php.
• Removed not using database migration files.
• Removed test examples.
• Extended HTTP middlewares without any changes were replaced with vendors.
• Event service provider was cleaned: removed registration emailing.
• User model was cleaned: removed useless doc-blocks, traits, notifications.
• Created environment variables for application timezone, locale.
