Colin Young 08ba14b03d Improve file blob upload diagnostics (#32305) ...

## Why

Blob upload failures previously surfaced the full signed upload URL and offered limited information for diagnosing transport and service errors.

## What changed

- Add a unique `x-ms-client-request-id` to each blob upload.
- Report transport failures with the upload host, elapsed time, error category, and client request ID, while stripping the signed URL from the underlying error.
- Report unsuccessful responses with Azure request and error IDs, and emit structured warning events with upload metadata and available Azure and Cloudflare identifiers.

## Testing

- Verify successful uploads include the client request ID header.
- Verify response and transport errors expose diagnostic fields without leaking signed URL parameters or response bodies.
