Fix NE page lint errors, topology tree overflow and NE row height.

- NE page: derive the live connect-detail row instead of syncing it in an
  effect; one async path for topology deep links; memoize per-tag stats;
  re-seed the form dialog during render on open; move hop form state into
  lib/hopProxy so the component file only exports components.
- NE page: drop the "click a card to filter" hint; keep row actions on one
  line so rows no longer double in height.
- Topology tree: rows fit the sidebar, long names ellipsize with a tooltip,
  node counts stay visible; default sidebar width 260 -> 280.
