Paul Payne 80c0d6b0ac Fix zulip 12.x env vars, try open-webui v0.10.0 intermediate upgrade ...

- zulip: rename legacy env vars per 12.x migration guide
  (DB_HOST -> SETTING_REMOTE_POSTGRES_HOST, etc.)
  Remove DISABLE_HTTPS/SSL_CERTIFICATE_GENERATION (HTTP is default in 12.x)
  Re-enable slot 12 as latest
- open-webui: try v0.10.0 as intermediate step from v0.9.5
  (v0.12.4 had duplicate column migration error jumping from v0.9.5)
