/**
 * Reject every still-pending proposal the assistant staged in one conversation.
 *
 * When the assistant proposes several verifikat and the user approves only some,
 * the rest linger as pending_operations in Granskning until the 30-day expiry —
 * the "manually clean up afterward" friction users reported. This clears the
 * leftovers in one shot: the chat's "clear the rest" button and the auto-clean
 * on conversation archive both call it.
 *
 * Only `status = 'pending'` rows are touched (never a committing/committed one,
 * which would stamp 'rejected' over a posted verifikat — the same guard the
 * single/bulk reject routes use). Company-scoped. Returns how many were cleared.
