MapProviderDrawer: fix verified-icon alignment + header padding

- Cluster rows: mirror desktop ClusterPopup's alignment recipe — add
  justifyContent: 'center' on the verified-icon slot and an explicit
  lineHeight: 1.25 on the name Typography. Before: the slot's 1.25em
  computed off the inherited 16px while the body2 name computed off
  14px, producing a ~2.5px mismatch that put the tick slightly above
  the name's top line. Now the slot's vertical centre matches the
  name's line-box.
- Drawer header padding: px 1.5 → 2 so the "N providers in this area"
  heading aligns horizontally with the row content beneath it
  (rows use px: 2). Previously the heading sat slightly further left.
