As an administrator, I want to customize permissions when assigning roles to users, so that I can adapt access rights according to specific business needs.

1: Add additional permissions to a user:
Given a user has a role assigned for an application
And the role contains predefined permissions
When the administrator adds additional permissions to the user's assignment
Then the system grants these permissions to the user
And the original role permissions remain unchanged.

2: Remove inherited permissions from a user:
Given a user inherits permissions from an assigned role
When the administrator removes specific permissions from the user's assignment
Then the system revokes these permissions for the user
And the original role permissions remain unchanged.

3: Reset user permission customization:
Given a user has customized permissions for an assigned role
When the administrator removes the customization
Then the system restores the user's permissions to the original role permissions.
