Keep the pnpm importer specifier aligned with package.json

This lockfile change updates the Penpal importer to @tailwindcss/postcss: ^4.2.2 here (and tailwindcss: ^4.2.2 a few lines below), but apps/penpal/frontend/package.json still declares @tailwindcss/postcss: ^4.2.1 and tailwindcss: ^4.0.0 on lines 31 and 45. pnpm install --frozen-lockfile is documented to fail when the lockfile is "out of sync with the manifest", and our Penpal CI/release workflows run exactly that command in .github/workflows/penpal-ci.yml:67 and .github/workflows/penpal-release.yml:64. As written, this dependency bump will break those jobs until the manifest and lockfile are regenerated from the same package.json.
