Subject: [PATCH] rollover incomplete tickets to active sprint on sprint review
 completion

- Add rolloverIncompleteTodos(from, to) DB method: moves pending/in_progress/blocked
  non-archived todos to the target sprint
- PATCH /api/sprints/[id]: when reviewed_at + status=completed, auto-rollover to
  active sprint (via getActiveSprint or rotateSprintIfNeeded)
- Returns rolled_over count in response for visibility
