feat(workspace): check the git identity before cloning extra folders

The workspace's "Or clone repositories" box now reads GET /api/me/git and
checks every URL as it is typed: an SSH link while the account has no SSH
key is never sent and points to Settings → Git (make a key, add its public
key to the host); an HTTPS host with no saved login is flagged with an
optional login row, since a public repo needs none. The identity is re-read
when the window regains focus, and a refused SSH login links to the same
settings. The server's ECREDENTIALS / ESSHAUTH answers still decide.
