CI: Add MANUALLY_BYPASS_SUBMISSION flag to azure upload/publish task

[ragaskar]

The Azure Partner Center was observed to return spurious validation errors around offer logos when submitting via API. This can be bypassed this by submitting "manually" via the Partner Center UX, but we would still like the azure-image-upload-and-start-publishing job to run successfully to allow the remaining pipeline jobs to complete as expected.

This commit adds a manual bypass with a number of safety checks to minimize the possibility of issues if the bypass configuration is left in place.

To guard against accidentally leaving the bypass on, the flag value must be set to today's date in Pacific time (YYYY-MM-DD). A stale date causes the job to fail with instructions. Additionally the job verifies:

1. The expected image version and blob URL are already present in the offer JSON (confirming the manual submission actually happened).
2. The offer's publisher-signoff step is not "complete" (which would indicate the offer already published and a re-trigger is a mistake).

If all checks pass, the job logs a loud WARNING banner and exits 0 so the pipeline continues to wait-for-azure-publisher-signoff as normal.

Walkthrough

The Windows submission job now passes MANUALLY_BYPASS_SUBMISSION to the Azure publishing task. When set, the task validates the Pacific date, authenticates with Microsoft, verifies the expected image version and blob URL, and checks the publisher-signoff status. If validation succeeds, the task exits before the normal copy and publish flow. Otherwise, it reports an error or continues with the existing flow.

Merge Risk: 🟠 High · up to 121e0

The manual bypass can mark an offer successful for the wrong image or without publisher signoff, potentially allowing an incorrect or insufficiently reviewed Azure submission to proceed. These validation gaps should be fixed before merge.

Preserve the existing bypass behavior only for an exact URL match.

one issue seemed reasonable, I've fixed that. The other I'm not particularly concerned about.
