refactor(web-test): извлечены DOM-скрипты filter.mjs в dom/filter.mjs

Все 17 inline page.evaluate в engine/table/filter.mjs вынесены в
именованные dom-генераторы. Engine-модуль стал чистым orchestrator-ом.

Новое в dom/forms.mjs (shared с будущим S3 select-value):
- findSearchInputScript(formNum)        — поиск SearchString/ПоискаСтроки input
- findNamedButtonScript(text)           — кнопка a.press по innerText (Найти, OK)
- findCompareTypeRadioScript(form, idx) — радио CompareType#N#radio
- isFormVisibleScript(form)             — есть ли видимые элементы form{N}

Новое в dom/filter.mjs:
- findFirstGridCellCoordsScript          — координаты первой клетки грида
- findColumnFirstCellCoordsScript        — клетка по имени колонки (fuzzy header
                                           match с needDlb-fallback)
- readFieldSelectorInfoScript            — FieldSelector value + DLB coords
- pickFieldInSelectorDropdownScript      — выбор поля в FieldSelector DLB-edd
- readFilterDialogInfoScript             — Pattern id+value+isDate+isRef
- findFilterBadgeCloseScript             — × badge по имени поля
- findFirstFilterBadgeCloseScript        — × первого видимого badge (для clear-all)

Попутно: добавлен импорт readSubmenuScript (был pre-existing broken
import в Еще-fallback ветке Alt+F).

Метрики filter.mjs: 390 → 256 LOC (−134, −34%), inline page.evaluate
17 → 0. Регресс 09-filter / 02-crud / 05-table — зелёный.
