Summary

Add Autodiscover XML inspection and file export using HrGetAutoDiscoverXML.

• Prompt for an email address, retrieve the response, and display its UTF-8 XML in a read-only editor.
• Save the original response bytes to an XML file without re-encoding.
• Preserve service/stream errors, release returned streams, and report failures at the UI boundary.
• Add mocked tests for import forwarding, stream ownership, read/seek failures, and UTF-8 validation.

Fixes #43.
