UI: render non-play history moves as a dim lowercase tag

Per owner feedback: pass/exchange/resign/timeout rows in the move history now read
as a dim, parenthesised, lowercase tag — e.g. «(обмен)» — so they stand apart from a
scored word. The move.* catalog values are lowercased (resign RU → «сдаюсь»); the
parentheses and the muted colour (var(--text-muted)) are applied in the view via a
.ha.sys modifier.
