Helm Chart inconsistencies

[Kim Brose]

The Helm Chart or at least its documentation is inconsistent both with the rest of the documentation and in itself.

For example, 9002 is given as both the Appservice Port and the Widget Listener Port, when only the latter seems to be correct.

Much of this can be alleviated if templating was properly used, e.g. the same value for this port would be only defined exactly once in values.yml and then be used in any relevant places in the templates.
