Default workspace selection to first value

[mootari]

In the workspace selection we sort workspaces by role and name, but default the selection to the first unsorted value. Example:

Because this selection may appear arbitrary to users, we should instead preselect the first option in the list.

Maybe it would be better to make the API smarter about what the default workspace should be? Like, it could be the one you most recently deployed to?

Sounds good to me! Ideally we also show a hint like "you recently deployed to" to explain the default.

I'll file a PR to have /cli/user return the additional metadata.
