Attempt to make alternatives UI clearer

[kpdecker]

Got some feedback from my client guys on the new UI and they had some confusion on the alternatives UI. This attempts to clear that up.

• Add info button to collapse section so we always have something to display without needing awkward “object” and “array” prefixes.
• Remove type prefixes for nested objects
• Add padding for visual separation
• Add “Any of” prefix to make alternatives options clearer
• Remove static well

As a consequence of the info changes, we now have uniform handling for the well content across both root sections and nested UIs.

I'm nitpicking but I prefer Details over Info, do you mind ?
