These now all pass. What's changed:

• cd tests-js/docker && docker compose up (runs the tests against the js validator)
• Removed some fields that were empty in sample messages
• Updated the schemas so each message_type field is an enum of 1 value (ensures the validator knows how to use the right payload definition)
• Updated the header.destination fields to match the spec. We might need to rethink this for things like the configuration message
• This is validating with noAdditionalProperties:false - I need to update the javascript adapter to match.
