Role permissions stored in model_has_permissions instead of role_has_permissions

[tegarkalam]

Issue:
When assigning permissions to roles using syncPermissions() or givePermissionTo(), the relationships are stored in model_has_permissions table instead of the dedicated role_has_permissions table.

Expected:

• Role permissions → role_has_permissions
• User permissions → model_has_permissions

Actual:
Both stored in model_has_permissions due to polymorphic relationship in HasPermissions trait.

Question:
Is this intentional design? The role_has_permissions table exists but remains unused.
