migrate: replace zhipuai with zai-sdk to unblock pyjwt CVE fix (#17197)

## Summary

Old `zhipuai==2.0.1` SDK (MetaGLM/zhipuai-sdk-python-v4) requires
`pyjwt~=2.8.0`, which blocks upgrading pyjwt past 2.8.0 to address
active CVEs. The upstream project now recommends the maintained
successor [`zai-sdk`](https://github.com/zai-org/z-ai-sdk-python).

`zai-sdk` relaxes the pyjwt constraint to `>=2.9.0,<3.0.0`, allowing
pyjwt 2.13.0+. The embedding API surface (`client.embeddings.create`) is
identical, no functional changes required.
