// TestHumaTaskUnreadStatus ports v1's POST /tasks/:projecttask/read (no v1
// webtest exists). The action deletes the caller's unread entry for the task;
// there is no fixture file for task_unread_statuses, so the table starts empty
// and the test seeds the row it expects to clear.
//
// Note on the permission model: the v1 handler enforces nothing — CanUpdate is
// a hardcoded true and Update is an unconditional DELETE on (task_id, user_id).
// A task the caller can't see (or doesn't exist) therefore has no row to clear
// and the call succeeds as a no-op. The only thing actually gated is auth, so
// that is what the negative case covers.
