style(ops-web): unify table actions as circular icon buttons

Replace the mixed text-link / button action lists in Accounts,
AdminUsers, and SiteDomainMappings with a shared .table-actions-row +
.action-* class set in styles.css. Each row now renders compact icon
buttons (edit/delete/approve/revoke/key/kol/reset/play) tinted by intent,
matching the new KolSubscriptions console look.
