fix(huggingface): resolve huggingface-hub 1.x compat (#35524)

- Switch `TestHuggingFaceEndpoint` from `Llama-4-Maverick` +
`fireworks-ai` to `Llama-3.3-70B-Instruct` + `sambanova` — Maverick is
no longer routed to Fireworks in hub 1.x
- Switch `test_stream_usage` provider from `nebius` to `scaleway` for
`gemma-3-27b-it` — same provider routing change
