fix: override picomatch >=4.0.4 and vite >=6.4.2 to patch high-severity vulnerabilities

Resolves 3 high-severity vulnerabilities from pnpm audit:
- GHSA-c2c7-rcm5-vvqj: Picomatch ReDoS via extglob quantifiers (>=4.0.0 <4.0.4)
- GHSA-p9ff-h696-f583: Vite arbitrary file read via dev server WebSocket
- GHSA-4w7w-66w2-5vf9: Vite path traversal in optimized deps .map handling

Also addresses moderate GHSA-3v7f-55p6-f55p (picomatch method injection).

Remaining vulnerabilities (moderate/low) are in transitive dependencies
managed by @kinvolk/headlamp-plugin and @headlamp-k8s/eslint-config
which require upstream updates to those packages.
