fix(form-add): идемпотентная регистрация <Form>/<Template> в ChildObjects

form-add и template-add вставляли запись в ChildObjects безусловно.
Если форма/макет уже зарегистрированы (например, form-compile
регистрирует <Form>, не создавая файл метаданных, а затем вызывается
form-add) — возникал дубль <Form>/<Template>, ломавший валидацию.

Приведено к идемпотентной модели, уже применённой в form-compile и
meta-compile: перед вставкой ищем существующую запись по имени; при
наличии — пропускаем и печатаем "Already registered ... (skipped
duplicate)". Зеркально в ps1 и py, регрессионный тест-кейс.
