Allowed permissions in the user factory to be chained

[marcusmoore]

Description

This PR allows multiple permissions to be added when chaining off of the user factory.

Previously, trying to apply two permissions in this way:

User::factory()->viewComponents()->viewUsers()->create();

would result in only the second permission, being able to view users, to be applied.

This PR fixes that by calling a new method within all of the permission related factory states of the user model that appends the permission instead of overwrites it.

PR Summary

• Changes to User Permissions
  The main changes in this PR focus on user permissions. Previously, the value of user permissions was hard-coded. Now, the system uses a new and more flexible approach.

• Enhancement of User Permission Methods
  Several user methods, like superuser(), admin(), viewAssets(), createAssets(), editAssets(), and canViewReports(), are now leveraging the newly created appendPermission() method. Instead of assigning permissions directly, they add ('append') permissions using this new method, making it easier to edit or update these permissions later on without changing the base code in each of these methods.

• Introduction of appendPermission() Method
  This is a new function designed to improve flexibility and maintainability of code when dealing with user permissions. It allows developers to easily give or modify the permissions of users by just calling this method and providing the required permission info.

This update enhances the flexibility and scalability of user management. In the future, implementing new features or permissions will be significantly easier and quicker. This update is targeted to improve the overall efficiency and adaptability of our system.
