Action register & recommendation lifecycle

Tracks every recommendation across every study — owner, status, due date, overdue flag, inline status edits, and CSV export — through a full lifecycle with management-of-change revalidation hooks, so nothing from the workshop falls through the cracks and a MoC trigger can reopen a closed action instead of quietly leaving it closed.

• After a workshop, to make sure every recommendation gets an owner and a due date instead of living only in the study minutes.
• Reporting overdue safety actions to management across the whole portfolio of studies, not one at a time.
• A management-of-change event affects a previously-closed recommendation and it needs to be reopened and re-verified.
