Extract format_error and permission_set_badge_class functions into
MvWeb.RoleLive.Helpers module to eliminate code duplication between
Index and Show LiveViews.
Add actor parameter to load_user_counts and recalculate_user_count
in Index LiveView to ensure consistent authorization and policy
enforcement. Also add domain parameter for clarity.
- Add Users column showing number of users assigned to each role
- Load user counts efficiently in single query to avoid N+1
- Similar implementation to membership fee types member count
Add complete CRUD interface for role management under /admin/roles.
- Index page with table showing name, description, permission_set_name, is_system_role
- Show page for role details
- Form component for create/edit with permission_set_name dropdown
- System role badge and disabled delete button
- Flash messages for success/error
- Authorization checks using MvWeb.Authorization helpers
- Comprehensive test coverage (22 tests)
Routes added under /admin scope. All LiveViews load user role
for authorization checks. Form uses custom dropdown for permission sets.
