feat(hostinfo): shrink the Host Inspector contents to its width

[Atreus-X]

Summary

• The Host Inspector forced a 640px minimum on its content, and every table used fixed-pixel columns, so a narrow block scrolled sideways (fix(hostinfo): a narrow Host Inspector scrolls sideways #43 made that scroll possible; this makes it rarer).
• Each fixed-pixel column is now minmax(<small min>, <original px>), so tables compress before they scroll and look the same at wide widths.
• Overview cards use minmax(min(230px, 100%), 1fr) so a single card can shrink below 230px, and the disk rows get smaller minimums.
• The scroll floor drops from 640px to 480px, the smallest width the densest table (Processes) now holds. Below 480px it scrolls sideways as before.

Testing

• tsc --noEmit: 0 errors
• vitest run: 107 passed
• Layout is CSS only and not exercised in a running window. Manual check: narrow the Host Inspector block from ~900px down to ~480px on each tab (Overview, Network, Ports, Processes, Services, Docker) and confirm the columns compress with ellipsis, with no horizontal scrollbar until 480px.

Known limits

Cells truncate with an ellipsis as they compress. Hiding low-priority columns at narrow widths (instead of truncating) is not part of this change.

SSH / wsh

Not applicable: frontend layout only; the Host Inspector data path is unchanged.
