fix: override elliptic for GHSA-848j-6mx2-7j84

* fix: add elliptic override for GHSA-848j-6mx2-7j84

Add pnpm.overrides.elliptic to prevent version regression on
the transitive elliptic vulnerability (CVE-2025-14505).

Vulnerability path:
@kinvolk/headlamp-plugin → vite-plugin-node-polyfills →
node-stdlib-browser → crypto-browserify → browserify-sign → elliptic

Note: pnpm audit will still report the vulnerability until
upstream publishes elliptic 6.6.2+. This override safeguards
against pulling a worse version.

* chore: regenerate pnpm-lock.yaml with elliptic override
