Per request:
- Migration: add nullable 'description' to the roles table.
- RoleManager Livewire component + view at /admin/roles:
* Roles list table with per-row checkboxes for bulk selection (+ select-all)
and a 'Delete selected' bulk action (protected roles skipped).
* 'New role' opens a modal form with just Name + Description (and permission
checkboxes to assign).
* Per-row View / Edit / Delete buttons (View modal shows description,
counts and assigned permissions).
- Admin role stays protected (no rename/delete/lose 'manage all').
- /admin/users links to the new Roles screen; the phase-1 permission matrix
stays available via a 'Matrix view' link.
