NodeCountSummary

Node totals for the Nodes list header: how many nodes are online, how many the current filter shows, and how many are known in total.

This used to live in the app bar subtitle slot, where it was clipped by the fixed app-bar height and squeezed horizontally by the node chip plus two icon buttons — the single long string was ellipsized on most phones (issue #6268). Here it gets the full content width and, crucially, is free to grow vertically: each count is an independent label inside a FlowRow, so at large font scales or in verbose locales the labels reflow onto extra lines instead of truncating. No maxLines, no ellipsis, no autosizing anywhere in this component.

Screen readers get one coherent sentence via Res.string.node_count_template rather than three disjointed fragments.
