feat(windows-ops): Refactor drive-dependencies onto design system

Renders as a panel with CRITICAL → WARN sections, summary line that
IS the verdict (3 references · DO NOT DISCONNECT / N · review /
0 · safe), critical-section inline alert with OS-breaking warning,
and WARN truncation past 20 entries (shows 8 + "(N more)" + tip).

Footer adapts: ⬤ blocked (busted) for critical / • warnings / • safe.

Bugfixes during dogfood:
- Removed stale Write-Section header that lingered above the panel
- Replaced 'switch ($true)' fallthrough pattern with explicit
  if/elseif (switch fallthrough was emitting arrays, breaking
  string-typed param binding in New-TermSummary)

Dogfooded against Y (no deps → safe), E (6 user-profile symlinks
→ warnings), C (96 critical services + 320 search/run-key warns
→ blocked). All three states render with correct grouping, alerts,
and footer health indicator.
