Parse and persist UI metadata on editor page

[ohltyler]

Description

This PR adds end-to-end support of saving to, and reading from, the ui_metadata field in the indexed workflow:

• refactors and updates processNodes() to use the newly-implemented formikToComponentData() to update the underlying data field with the form values
• removes the filter in processNodes() which was limiting the fields that were saved. Defaulting to all fields now, so other metadata like position, positionAbsolute, extent, parentNode, etc. are saved. This allows proper functionality for the parent/child nodes that we have (e.g., nodes inside Ingest block), and nice-to-haves, like the exact node positioning within the viewport staying static such that reloads will still show the view exactly how the user last left it
• adds ui_metadata parsing in server-side when fetching workflows via searchWorkflows()
• improves the hook on props.workflow in ResizableWorkspace to only parse the state when there is a valid workflow. This is to prevent weird intermediate states where it may render a default/invalid template immediately before the target workflow is fetched and rendered on top. instead, we leave it empty and don't populate any nodes/edges until that the workflow is available

Misc changes:

• data model change in IComponentField from name -> id for consistency
• removes codecov and pre-commit hooks until project is more stable. added tracking in the existing issue to re-enable later on: see Re-enable linting and codecov mechanisms #109

Demo video:

• workflow state & node positioning persisted
• values persisted in workflow nodes and internally as initial values in the Formik <Form>
