Server: missing /Upgrade/Report route causes 404 during silent update #71

Describe the bug

The server registers both URL variants for Verification:

• /Upgrade/Verification
• /Update/Verification

But only one variant for Report:

• /Update/Report

When a client uses the /Upgrade/* URL convention (e.g., http://localhost:5000/Upgrade/Report), the report endpoint returns 404.

To Reproduce

1. Start the sample server
2. Run any client configured with reportUrl = "http://localhost:5000/Upgrade/Report"
3. Observe 404 errors during update status reporting

Expected behavior

/Upgrade/Report should work the same as /Update/Report, mirroring the Verification endpoint pattern.
