Add support for approval-based ticket merge workflows in AI flows and skills. After a duplicate ticket is detected, the system should allow a manager or technician to review and approve the merge before any action is taken. Suggested options include approval emails with Approve or Decline actions, or interactive buttons and links directly inside internal ticket notes that can trigger the merge once confirmed. The goal is to support safe, human-verified automation for duplicate ticket handling while keeping the review process quick and easy.
