fix: pin heyform to v0.1.0 and use valid keydb tag

- heyform/community-edition:latest now points at v3.0.0-rc.* which hangs
  after Mongoose init and never binds port 8000 (502 behind Traefik).
  Pin the last stable release v0.1.0 (boots and serves the UI).
- eqalpha/keydb:6.3.3 does not exist on Docker Hub; use the multi-arch
  alpine tag instead.

Deploy-tested on a Dokploy instance: HTTP 200, HeyForm UI renders.
