Update Next.js dependencies

[anumol-baby]

Summary

• upgrade Next.js from 16.2.6 to 16.3.0
• remove the obsolete PostCSS override now that Next.js pins a patched release
• update transitive PostCSS, Nano ID, Sharp, and native Sharp packages
• resolve the production dependency vulnerabilities reported by npm audit

Why

Next.js 16.3.0 updates its dependency chain to patched versions of PostCSS and Sharp. Updating the framework avoids maintaining application-level overrides for framework-owned dependencies and also picks up the current Next.js security fixes.

Validation

• npm ci
• npm audit --omit=dev --audit-level=high (0 vulnerabilities)
• npm run build
• git diff --check
