chore: adapt Dockerfile/compose for standalone server repo

- Dockerfile no longer bakes in a Flutter web build (this repo has no
  client/ dir); the web bundle is mounted at runtime instead.
- docker-compose.yml: web bundle mount path configurable via
  WEB_CLIENT_BUILD_PATH, defaults to a sibling KC-APP checkout.
- README: point to the KC-APP client repo for clients.
