Clean up overall form state

[ohltyler]

There is several layers to form state we are persisting:

• redux dirty variable for the overall form
• Formik values to trigger autosave when any form input is changed
• searchTemplatesDifferent/ingestTemplatesDifferent to maintain when the underlying generated templates would be different

Determine if we need all of these (particularly dirty) or if there are any that can be cleaned up, simplified, or combined.
