refactor(validation): implement centralized validation patterns across components

- Introduced `ValidationPatterns` class to standardize validation rules and messages for various fields across multiple components.
- Updated components including `General`, `StackForm`, `Create`, and `Show` to utilize the new validation patterns, ensuring consistent validation logic.
- Enhanced error messages for required fields and added regex validation for names and descriptions to improve user feedback.
- Adjusted styling in the `create.blade.php` view for better visual hierarchy.
