fix(providers): rename OpenCode/OpenClaw Kimi preset to "Kimi"

The OpenCode and OpenClaw presets were labeled "Kimi K2.7 Code", unlike
the plain "Kimi" used by the other apps. Rename the preset (and the
OpenCode provider display name) to "Kimi" for consistency; the model
label stays "Kimi K2.7 Code" since it describes the actual model.
