feat(form-compile): ValuesPicture для PictureField

PictureField, привязанный к булеву/числу, без ValuesPicture не рисует
иконку. Добавлены ключи DSL:
- valuesPicture: ref картинки значения (StdPicture.*, CommonPicture.*)
  → <ValuesPicture><xr:Ref>…</xr:Ref></ValuesPicture>
- loadTransparent: true → <xr:LoadTransparent>true</xr:LoadTransparent>
  (выводится только при true)

Реализовано в обоих портах (ps1 + py, v1.22), добавлены в whitelist
свойств. Регресс: новый кейс picture-field (picField + ValuesPicture +
CheckBoxField + событие Selection), эталон зелёный на ps1 и py, плюс
платформенная form-validate.
