bug(console): Team and contacts email selection doesn't persist

[betimshahini]

When selecting an email from the email dropdown in the Team and contacts page, the selection does not persist, nor does a toast message show up. No network calls are being sent as part of the selection.

Root cause is with inconsistent return types of DropDownListItem and the value property contained within it, where in some parts of the codebase one is expected but the other is returned.
