refactor(web-test): этап B.5.5 — ввести returnFormState (выборочно применить)

core/helpers.mjs: returnFormState(extras) — стандартный хвост action-функций:
getFormState + Object.assign(extras) + checkForErrors → state.errors. Унифицирует
~15 hand-written копий и закрывает R1/R2/R3 (state.errors теперь добавляется
автоматически у любого пользователя хелпера).

В этом коммите конвертированы только 2 простейших P1-сайта (openCommand,
второй handle в navigateLink) — без extras между getFormState и err-проверкой.
Остальные 30+ сайтов сложнее (state.X между, разные return-shape, wrapped
fillFields) — будут мигрированы органически при переносе clickElement/
selectValue/closeForm в forms/* на этапе C.
