Update Key Results Progress

Update the progress (check-in) of one or more key results for a specific goal without changing the goal status.

Note: This endpoint behaves like the check-in mechanism in Bob, however, it maintains the current goal status, updating only the key result progress. To update the goal status, use the Update Goal Status endpoint.

This endpoint supports optional audit fields at both levels: goal-level comment and key result-level notes. These parameters only affect check-in activity log for auditing purposes. They are not part of the Goal or Key Result entities, and are not returned by search/metadata endpoints.
