[Workplace Search] Migrate additional shared source components (#83850)

* Initial copy/paste of components

Changes for pre-commit hooks were:

- Linting
- Lodash imports
- remove `any` type in favor of React.ReactNode
- Move setState to top of component

* Add image

* Update component paths

* Remove reference to ConfirmModal

Since all the legacy component does it wrap the EUI component we decided to drop it.

Legacy:
https://github.com/elastic/ent-search/blob/master/app/javascript/shared/components/ConfirmModal/ConfirmModal.tsx

* Remove local flash messages in favor of global flash messages

* Various type fixes

* Fix image location
