Enable Full List of Measurements in Data Explorer

## User Story

As a user, I want to be able to see a full list of measurements when browsing in the schema browser, so that I can select any item that is in the list.

## Acceptance Criteria

- There will no longer be a limit if 200/500/1000 as to the number of items that can be shown

- When a large list is gathered (over 1000 possibly), which might cause performance issues, the list will get shown in chunks (via show more or other control

- Limit of 200/500/1000 will be removed

## Notes

Recommendation from Ari:

- Update the Dropdown component in clockface to paginate results with endless scrolling so that only a subset of the items are ever displayed to the user and the component is still performant

Original spike making this recommendation:

Start with the Dropdown component in clockface and review the linked spike in issue 5003 for the pagination recommendation. Implement chunked or endless scrolling so large measurement lists remain performant and the 200/500/1000-item limits are removed; done means users can access the full list in the schema browser.
