Pull request overview

Fixes az stream-analytics input create not sending authenticationMode for Blob-based inputs, which prevented Azure Policy (deny non–Managed Identity auth) from evaluating correctly.

Changes:

• Add authentication_mode/authenticationMode serialization mappings to vendored Stream Analytics SDK models for Blob datasource/input types.
• Add a scenario test that validates policy denial occurs when creating a Blob input with authenticationMode=ConnectionString.
• Update/add VCR recordings for the new test and for storage API-version drift in existing input CRUD recordings.
