Subject: [PATCH] Drop unused Default field from cmdio.PromptOptions

No production caller sets it. databricks auth login renders the default
in the label and substitutes it manually on empty input (PR #3252), and
no other prompt uses it. Also drop the --default flag from selftest tui
prompt, which only existed to exercise the field.
