Add web SVG generator, container, and Kubernetes manifests

- Flask app (web/) generates M1730 scale SVGs from a form; embeds
  GOST typ A font as base64 so output is self-contained
- Dockerfile builds the app into git.baumann.gr/adebaumann/m1730-generator
- k8s/ deploys as a ClusterIP service for NPM to proxy at
  works.adebaumann.com/M1730-generator/
