Jamie hide unnecessary run buttons in workflow

[jamiewaese-uncharted]

Just cleaning up the workflow nodes a bit. For instance:

• hide run buttons that are disabled
• make help message type settings consistent

BEFORE

AFTER

Here are all the nodes hooked up properly. The 'Run' buttons appear as they should.

I have changed from using modelColumnNames in these v-ifs to using modelConfigId and datasetId
If we are having logic to check if we have inputs on the nodes then we should use the values directly computed from the node's inputs rather than the column names that are derived later
