feat(roles): Rappasoft list, slim create form, and 2-tab role view

1. Roles list now uses a Rappasoft table (RoleTable): search/sort, per-row
   view/edit/delete, and built-in bulk selection + 'Delete selected'. The
   /admin/roles page is a plain view embedding <livewire:role-table />.
   RoleForm create/edit now only has Name + Description (permissions removed).
2. New RoleView page (/admin/roles/{role}) with two tabs:
   - 'Details': header with role name + Back button; description with Edit/Delete
     buttons; table of users holding the role (avatar+name | last name | status).
   - 'Permissions': all permissions grouped by section (by resource), each with a
     toggle switch to grant/revoke for this role (Admin keeps 'manage all').
Removed the old RoleManager component/view (superseded).
