fix(catalog): extend stream idle floor to kimi k2.7 code

Native Kimi K2.7 Code (kimi-k2.7-code / kimi-k2.7-code-highspeed) reasons
for minutes before the first stream event like K2.6, but the
streamIdleTimeoutMs branch in buildOpenAICompat gated only on
isKimiK26ModelId, so K2.7 Code fell through to the 120s default and
aborted on long reasoning turns. Match matchesKimiK27CodeFamily in the
same branch and rename the constant to KIMI_REASONING_STREAM_IDLE_TIMEOUT_MS.

Fixes #4836

+- Extended the reasoning `streamIdleTimeoutMs` floor (300s) to native Kimi K2.7 Code (`kimi-k2.7-code` / `kimi-k2.7-code-highspeed`), which previously fell through to the 120s default and aborted on long reasoning turns ([#4836](https://github.com/can1357/oh-my-pi/issues/4836)).
