chore: initial infrastructure scaffold

Kustomize base + overlays for the full Sunbeam k3s stack:
- base/mesh      — Linkerd edge (crds + control-plane + viz)
- base/ingress   — custom Pingora edge proxy
- base/ory       — Kratos 0.60.1 + Hydra 0.60.1 + login-ui
- base/data      — CloudNativePG 0.27.1, Valkey 8, OpenSearch 2
- base/storage   — SeaweedFS master + volume + filer (S3 on :8333)
- base/lasuite   — Hive sync daemon + La Suite app placeholders
- base/media     — LiveKit livekit-server 1.9.0
- base/devtools  — Gitea 12.5.0 (external PG + Valkey)
overlays/local   — sslip.io domain, mkcert TLS, Lima hostPort
overlays/production — stub (TODOs for sunbeam.pt values)
scripts/         — local-up/down/certs/urls helpers
justfile         — up / down / certs / urls targets
