chore: update pnpm lockfile to resolve dependency conflicts

Updated pnpm-lock.yaml via clean install to ensure all @objectstack packages are on consistent 4.0.3 versions.

Note: There's a validation warning from @objectstack/spec@4.0.3 regarding Setup app navigation labels, but this is an upstream issue and doesn't affect functionality. The dev server starts and runs successfully.
