feat(web-test): поддержка гридов без шапки (headerless grids)

Единый источник деривации колонок для безголовых гридов (без .gridHead):
synthHeaderlessColumns (HEADERLESS_GRID_FN в _shared.mjs) — привязка по
colindex, имена Колонка{N}/(checkbox)/(picture), расщепление комбинированной
марк-ячейки (галка+текст в одной .gridBox) на (checkbox)+Колонка1 через subTarget.

Ветки head ? существующее : synth добавлены в:
- readTableScript, findGridCellScript, scanGridRowsScript,
  findGridHeadCenterCoordsScript (grid.mjs)
- findCellCoordsByFieldsScript, findNextCellCoordsByKeyScript,
  sortFieldKeysByColindexScript, readActiveGridCellScript (grid-edit.mjs)
- сводка таблиц в READ_FORM_FN (_shared.mjs)

Гейт — неизменная истинность head, headed-путь нетронут. Регресс 23/23 зелёный.
Новый tests/web-test/21-headerless.test.mjs. Live на БезшапочнаяТаблица +
МножественныйВыбор: readTable/getFormState/fillTableRow(тоггл (checkbox))/clickElement.

Follow-up: правка data-ячейки на безголовом ValueTable (edit-Tab-loop row-fill).
