MAT-9816: Add admin user profile library delete coverage - #3095

Summary

Adds Cypress coverage for MAT-9816 Admin User Profile library deletion and MAT-9892 admin single-instance library deletion.

Changes

• Added requestAdminCqlLibraryDeleteById(...) to TestData.
• Added MAT-9892 service coverage for deleting a single version by document ID and validating owner HARP ID protection.
• Added Admin User Profile library Delete action-state coverage:
  • No selection disabled.
  • Latest draft/version enabled.
  • Historical version disabled.
  • Multiple selection disabled.
  • Owned and Shared Libraries.
  • QI-Core and QDM coverage.
• Added Admin User Profile delete-dialog coverage:
  • Draft/version-specific confirmation text.
  • Warning, separators, red delete button.
  • Cancel and close-X behavior.
• Added regular-user delete-dialog Cancel and close-X regression coverage without duplicating existing successful-delete coverage.
• Updated the Cypress refactor backlog with the resolved MAT-9892 admin-scope finding.

Validation

• npm run compile
• npm run quality:no-focused-tests
• git diff --check
• DEV: AdminUserProfileLibraryDeleteActions.cy.ts — 5 passing.
• DEV: CQLLibraryDeleteDialog.cy.ts — 2 passing.
• DEV: MAT-9892 service scenarios passed.

Known DEV Gaps

The active Admin User Profile confirmation tests document two product issues:

• Owned draft deletion returns 403 for an admin instead of 200.
• Shared version deletion calls the correct MAT-9892 endpoint but sends the selected shared user’s HARP ID instead of the actual library owner’s HARP ID, resulting in 409.

Risk

Low. This PR changes Cypress coverage and shared test helpers only.
