Let the reviewer fill out the IRA questionnaire themselves. Cancels any outstanding request and opens a blank response addressed to the reviewer, which they then fill in and submit through the normal form endpoints (GET/PUT /forms/response/{id}, POST /forms/response/{id}/submit) — that submit path already triggers the same scoring as a vendor submission.

A task that skipped the questionnaire at review creation (manual_override, form_id null) has no form to reuse — this instead creates one from the review flow's configured IRA template, if any. That form-less path is also available on an already-completed task, mirroring "send questionnaire" (reassign): a reviewer who set the assessment manually may change their mind and fill out the real questionnaire after all, which reopens the task.

A task with an actual form can only be self-completed while still pending — once it's completed, the assessment is terminal and this is no longer available for it.
