The interactive `config init` flow showed a QR code and verification
link without indicating their relationship, leaving users unsure
which to act on first and whether the link was still needed after
scanning.
Split the message strings on TTY vs non-TTY:
- TTY: header above QR ("使用飞书 / Lark 扫码配置应用"), "或打开链接"
framing to mark the link as an alternative, and an active waiting
indicator.
- Non-TTY (AI / piped callers via --new): keep the original copy
verbatim so existing parsers and prompts are unaffected.
QR is still rendered in both branches.
