freeform template: coder-routes needs work, not yet reliable or correct

[rfay]

I am experimenting with doing a new ddev/ddev.com blog on coder.ddev.com freeform template, and I note some problems:

On start, we see ports 80/8025/4322 properly explained:

Building Coder Traefik routes from ddev.com_merged.yaml:
  + perf: http-80 → ddev.com-web-80  (https://perf--perf--rfay.coder.ddev.com)
  + mailpit: http-8025 → ddev.com-web-8025  (https://mailpit--perf--rfay.coder.ddev.com)
  + perf: http-4322 → ddev.com-web-4321  (https://4322--main--perf--rfay.coder.ddev.com)
✓ Wrote coder-routes.yaml

But ddev launch doesn't have as many of them and they don't actually match:

coder@perf-rfay:~/ddev.com$ ddev launch

Coder URLs for project 'ddev.com':
  Web:     https://80--main--perf--rfay.coder.ddev.com
  Mailpit: https://mailpit--perf--rfay.coder.ddev.com

And https://4322--main--perf--rfay.coder.ddev.com/ and https://80--main--perf--rfay.coder.ddev.com don't work at all
