fix: normalize terminalBackground default and drop unrelated lockfile churn

Follow-up to the salvaged terminalBackground commit:
- align the CSS-var fallback and type doc to the runtime default (#000000)
- revert web/package-lock.json to main (the original commit stripped peer
  flags as an npm-version artifact, unrelated to the feature)
