Penpot MCP server (mcp-designer.sunbeam.pt):
- Pre-built Node.js image pushed to Gitea registry

Wildcard TLS:
- Switched cert-manager from HTTP-01 (per-SAN) to DNS-01 via Scaleway webhook

- Added scaleway-certmanager-webhook Helm chart
- VSO secret for Scaleway DNS API credentials in cert-manager namespace
