ignore erroneous test (2.13 ONLY)

imprecise totalCount to avoid requiring admin permission

(this is a temporary hack for 2.12; the non-admin caller of this method is removed in 2.13 and later)

frontend: correct docker:cmd directive form

`serve` is treated as a shell form and hence runs:

```
/sbin/tini -- /usr/local/bin/frontend /bin/sh -c serve
```

Which is incorrect. Instead, we want `["serve"]` which is treated as parameters
to `ENTRYPOINT` by Docker, i.e.:

```
/sbin/tini -- /usr/local/bin/frontend serve
```

frontend: specify default serve command arg

So that we do not need to specify it as part of deployment, i.e. we can remove:
