Finalize edit flow for ingest inputs

[ohltyler]

Description

This PR finalizes all create and edit states for the ingest flow configuration. Specifically:

• updates buttons to be consistent, and be enabled/disabled based on the form and edit state
• updates edit flow to have a 'Delete resources' button, which opens a confirmation modal to confirm deletion. if deletion is selected, revert to the create state, but defaulted to the 'skip' option.
• updates search flow to have a dynamic index configuration; if ingest is configured, enforce the search flow is against the configured index. if ingest is not configured/skipped, then provide a dropdown listing out available indices the user can select to run the search flow against

Demo video showing the create and edit states, new buttons, resource deletion confirmation, and the 2 different states of the configured index on the search flow:

On the pop-up for delete confirmation should we mention which resources we are deleting, or mention when we are deleting an index?

Current mocks don't show those specifics. We can always tune later. We don't have any finalized wording.
