chore(deps): npm audit fix — bump transitive undici to clear advisories (#49113)

Resolves the 2 npm audit advisories (1 high, 1 moderate), both from
transitive undici:
- undici 6.26.0 -> 6.27.0 (high: TLS bypass / header injection /
  response queue poisoning class, via node-gyp + ui-tui)
- jsdom's undici 7.27.2 -> 7.28.0 (moderate, via jsdom test dep)

Both are in-range bumps (no --force). Lockfile also reconciled two
pre-existing manifest drifts during the install: dompurify 3.4.10 ->
3.4.11 (in-range patch) and the web workspace's already-declared
vitest ^4.1.5 devDep. No package.json changes. npm audit reports 0
vulnerabilities in root, ui-tui, and apps/desktop after.
