feat(ui): add button to go to model manager next to all model combobox

[psychedelicious]

Summary

• Add a button to go to the model manager next to every model combobox.
• Add onClickGoToModelManager prop to override what the button does. If this is provided, the button will render, even if the model manager is set as a disabled tab (the tab will not render).
• Abstract out the workflow editor's model input field component. Previously every model field copied the same combobox components and there were subtle inconsistencies across them - now they are all identical (and have the model manager button).

Well, it turns out that is a crapload of added buttons. Too many? Maybe. Demo:
