feat(form-decompile,form-compile): командные панели (кластер D)

- form-decompile: форменный AutoCommandBar → autoCmdBar-элемент; ButtonGroup;
  команды tooltip/currentRowUse; choiceList value type (число/булево) — раньше.
- form-compile (PS1+PY): новый тип ButtonGroup; команды ToolTip/CurrentRowUse.
- docs/form-dsl-spec: buttonGroup, autoCmdBar (панель формы), tooltip/currentRowUse.
- tests: кейс form-compile/button-group (+snapshot, платформенно валидирован).

АварийныйРежим раундтрип: diff 44→18. Регресс form-compile зелёный (PS1+PY).
