Add follow_up_outcome and follow_up_resolved_at to consents

When a nurse follows up with a parent who requested a discussion before refusing, the outcome needs to be recorded on the existing consent. These columns track whether the follow-up resulted in the refusal being confirmed or withdrawn, and when that resolution took place - enabling the activity log to reflect the full follow-up history accurately.
