### What problem does this PR solve?
when use azure blob as the file container, when click parse file, it
calls:
```python
partial(settings.STORAGE_IMPL.put, tenant_id=task["tenant_id"])
```
So any storage backend used there must accept tenant_id as a kwarg.
RAGFlowAzureSasBlob.put() did not, causing:
```
TypeError: ... got an unexpected keyword argument 'tenant_id'
```
Now it does, so parsing should proceed past this point.
### Type of change
- [x] Bug Fix (non-breaking change which fixes an issue)
## Summary
- The Azure SPN storage handler hardcoded
`AzureAuthorityHosts.AZURE_CHINA`, preventing users in Azure Public
Cloud regions (UK-South, EU, US, etc.) from authenticating
- Add a `cloud` config option (env: `AZURE_CLOUD`) supporting all four
Azure sovereignties: `public`, `china`, `government`, `germany`
- Defaults to `public` (global Azure) — the most common international
use case
Closes#13259
## Test plan
- [ ] Verify default (`cloud: public`) connects to Azure Public Cloud
endpoints
- [ ] Verify `cloud: china` retains existing behavior for Azure China
users
- [ ] Verify `AZURE_CLOUD` env var overrides the config file value
