Update to Use New casts() Method in Laravel 11

[bloopdex]

With the release of Laravel 11, the casts property has been deprecated and replaced by the new casts() method. This issue seeks to facilitate the transition by updating our codebase and documentation accordingly.

Tasks:

1. Update Code Examples: Refactor all instances in our codebase where the casts property is used to utilize the casts() method instead.

2. Revise Documentation: Modify the project documentation to reflect the changes in Laravel 11, ensuring it clearly explains the new method and its usage.

3. Check for Compatibility: Review the code for any potential backward compatibility issues and document any necessary migration steps for users.

4. Add Tests: Implement unit tests to verify that the casts() method functions as expected in our context.

Expected Outcome

By completing this task, we will ensure that our project remains compatible with Laravel 11 and provides clear guidance for users on how to implement the new casts() method effectively. This will enhance usability and reduce confusion for developers upgrading to the latest version.
