fix(ui): open the test 7 settings screen only on a real terminal

The screen was gated on raw-mode availability alone, so `-t 7` with stdout
redirected (`> out.txt`, `| tee`) still painted it and then waited forever for a
keypress nobody could send. It now requires a terminal on both ends — stdin to
answer it and stdout to draw it — and falls back to the CLI flags otherwise,
which is what `--burst`/`--burst-timeout`/`--burst-profiles` are for.

Found by the release smoke test: the piped run hung until the harness deadline.
