fix(web): pin Next SWC binaries and regenerate lockfile with CI's npm

Since the SDK 56 dependency churn, arborist nests next under apps/web and
npm 10 skipped its platform-optional SWC binaries on the x64 CI runner,
breaking next build. Pin the linux and darwin binaries as direct
optionalDependencies of @sauci/web (bump alongside next) and regenerate
the lockfile from scratch with npm 10.8.2 to match CI. Verified in a
linux/amd64 node:20.19.4 container: npm ci installs the binary.
