feat(004): Add RBAC and Group permissions to config

Added two new required permissions for Feature 004:
- DeviceManagementRBAC.Read.All: Resolve scope tag IDs to names
- Group.Read.All: Resolve group IDs for assignments

These permissions will be displayed on the Tenant detail page
(/admin/tenants/1) as 'missing' until added in Azure AD.

Steps to complete setup:
1. Add permissions in Azure AD App Registration
2. Grant admin consent
3. Move permissions from 'Required' to 'Tatsächlich granted' in this config
4. Clear cache: php artisan cache:clear
5. Verify on Tenant detail page
