React Server Components security update

The dashboard dependency set moved to patched React and Next.js releases for the relevant React Server Components advisory. The change was dependency-focused and did not alter ZKAuth authentication protocols.

The update was applied to the dashboard surface that renders server components. Engine proof verification and SDK protocol inputs remained separate from this framework patch.

The repository retained its normal lint, type-check, unit, and production-build gates after the dependency move. This entry records patch adoption, not a claim that one dependency update closes every application-level vulnerability.
