fix(cli): add quiet zone around terminal QR; fix q-key quit via /dev/tty

- renderToTerminal now pads with a 4-module quiet zone (white border)
  horizontally and vertically, matching the webapp rasterizer.
- Keyboard input now tries /dev/tty first so q/Ctrl-C works even when
  stdin is a pipe (e.g. echo ... | bun run src/cli/qr-terminal.ts).
- Update all CLI renderer tests for padded output; add tests for custom
  and zero quiet zone.
- Increase outer_ec_benefit test timeout to 15s to avoid flaky failures.
- Rebuild CLI bundle and webapp; redeploy to nginx.
