fix: add timeout to requests calls in oauth.py

- Add timeout=60 to requests.post() in retrieve_token() (line 209)
- Add timeout=60 to requests.get() in get_azure_entra_id_workspace_endpoints() (line 548)
- Add timeout=60 to requests.post() in PATOAuthTokenExchange.refresh() (line 916)

This prevents indefinite hangs when OAuth endpoints are unreachable or slow,
matching the SDK's default http_timeout_seconds of 60 seconds.

Resolves #1338
