chore(kimi): update referral links to new platform.kimi.com domain

Moonshot rebranded its console to Kimi, so refresh all Kimi sponsor
referral links across provider presets and READMEs:

- API (domestic): platform.moonshot.cn/console -> platform.kimi.com
- API key page: platform.moonshot.cn/console/api-keys -> platform.kimi.com/console/api-keys
- Coding Plan: www.kimi.com/code/docs/ -> www.kimi.com/code/

Also add the missing ?aff=cc-switch param to the codex and openclaw
entries that previously had no referral attribution. API endpoints
(api.moonshot.cn, api.kimi.com/coding) are intentionally left unchanged.
The overseas link (platform.kimi.ai) is not wired up yet since there is
no overseas API preset.
