Show cloud agent env name and setup status for vertical tabs pwd (#11006)

## Summary

There was a weird UI pattern where, after kicking off a cloud run, the
directory and branch (which falls back to the directory when there's no
branch info) in the vertical tabs would be empty. This looked especially
bad if the directory was your vertical tabs title, as then the title
would just be empty.

The fix is to show:
* "Environment <dot> setup status text" while the environment is
starting up and
* "Environment <dot> pwd" when the environment is set up (this isn't
solving the first problem, but it's nice to know what env you're in from
vertical tabs so @zachbai and I figured it made sense to add)
