Restore the dependency upgrades I reverted

The merged Renovate bumps were undone when I rsync'd a local tree over these repos while
pushing the contract tests — that local package.json was a pre-merge backup I had kept so
the PRs would be the source of the versions.

Re-applied and verified from a clean install (rm -rf node_modules package-lock.json &&
npm install && tsc && vite build), which is also what regenerates a lock file consistent
with all the bumps at once.
