Make dashboard cards uniform and symmetric; stop clipping update text

The four welcome cards varied in shape and typography: the grid
produced a 3+1 orphan layout at wide widths, sub text was
single-line ellipsized (the updates card ended mid-sentence with
"…"), the Network card's values used a different size than the
other cards' sub text, and only the clickable cards carried a
chevron circle.

- Grid is now a symmetric 2×2 at wide widths (equal-height rows);
  the three-card Desktop-only role renders one balanced row
- Card sub text wraps instead of being cut off — "Sovran_SystemsOS
  keeps itself current" is fully visible at every width
- One type scale across all cards: 0.9rem titles, 0.8rem sub text
  (Network values aligned to it), 46px chips, uniform min-height
- Chevron circles removed from the cards — hover/focus lift is the
  click affordance, and every card has the same shape
- The updates card now reflects the real update state (failed,
  restart required, running) instead of only "updates available";
  it can no longer claim up-to-date while a restart is pending
