feat(devtools): deploy Penpot + MCP server, wildcard TLS via DNS-01

Penpot (designer.sunbeam.pt):
- Frontend/backend/exporter deployments with OIDC-only auth via Hydra
- VSO-managed DB, S3, and app secrets from OpenBao
- PostgreSQL user/db in CNPG postInitSQL
- Hydra Maester enabledNamespaces extended to devtools

Penpot MCP server (mcp-designer.sunbeam.pt):
- Pre-built Node.js image pushed to Gitea registry
- Auth-gated via Pingora auth_request → Hydra /userinfo
- WebSocket path for browser plugin connection

Wildcard TLS:
- Switched cert-manager from HTTP-01 (per-SAN) to DNS-01 via Scaleway webhook
- Certificate collapsed to *.sunbeam.pt + sunbeam.pt
- Added scaleway-certmanager-webhook Helm chart
- VSO secret for Scaleway DNS API credentials in cert-manager namespace
- Added cert-manager to OpenBao VSO auth role
