OCPBUGS-109746: OCPBUGS-112085: CORS-4441: Bootimage controller should gracefully handle Azure gen1 image removal

[djoshy]

- What I did

• Removes hard error if the gen1 imageset is missing.
• Added detection of the new gen2 formatting.
• Added a fix for Confidential clusters: the skips were not being accurately returned in this case (OCPBUGS-109746)
• Also added a fix for testing bug which broke Azure bootimage tests (OCPBUGS-112085)
• Added/Fixed units to verify the above.

This is a companion PR to openshift/installer#10764, order of merging does not matter as I don't think there are any gen-1 clusters in CI. The MCO only uses gen2 images in testing.

- How to verify it
Azure bootimage updates e2es and related units can be used to verify this.

Summary by CodeRabbit

• Bug Fixes
  • Improved Azure image reconciliation for marketplace SKUs containing gen2.
  • Missing Gen1 images are now skipped without causing reconciliation errors or unnecessary updates.
  • Available Gen2 images continue updating to newer versions, including after Gen1 image removal.
  • Azure security-profile exclusions are now handled as skipped reconciliations.
  • Missing Gen2 images and unsupported image variants continue to be reported as errors.

Walkthrough

Azure image reconciliation recognizes gen2 marketplace SKU markers and skips missing Gen1 images without patching. Gen2 images continue to update when newer stream data exists. Tests distinguish skipped reconciliation from patch requirements and use Azure-compatible image values.

Changes

Azure boot image reconciliation

Layer / File(s)	Summary
Image selection and skip propagation pkg/controller/bootimage/platform_helpers.go	Marketplace detection recognizes v2 and gen2 SKU markers. Missing Gen1 images return a skip status. Unsupported variants, missing image sets, and missing Gen2 images remain errors.
Reconciliation skip test contract pkg/controller/bootimage/boot_image_controller_test.go	Tests assert reconcileSkipped separately from patchRequired. Coverage includes missing Gen1 data, Gen2 updates, and security-profile skips.
Platform-aware extended tests test/extended-priv/mco_bootimages.go	Tests use platform-specific fake images. Azure comparisons use only the image resourceID.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to dd98f

This PR updates Azure boot-image handling for missing Gen1 images and Gen2 image formatting, with related test coverage; no actionable merge-blocking risk remains after normal checks and review.
