Remove all client-side map munging (#60701)

Remove the getCytoscapeElements function.

On the server:

* Replace `source` with `sourceData`, `destination` with `targetData`, `source.id` with `source`, and `destination.id` with `target`.
* Return a single array as an `elements` property instead of `nodes` and `connections`
* Map all of the items data to be inside of a `data` object
* Replace SERVICE_AGENT_NAME with AGENT_NAME
* Add some missing constants

On the client:

* Remove getCytoscapeElements
* Move all presentation-specific data transformation to use the original attributes in the place where they're needed
* Remove `href` since it wasn't being used
* Move BetaBadge to its own file
* Move cytoscapeDivStyle to cytoscapeOptions
* Fix storybook to work with new data formats
