test(designsystem): Roborazzi screenshot-каркас — рендер Compose в PNG на JVM (Fd-сверка без эмулятора)

Пилот: F7PrimaryButton/F7SecondaryButton рендерятся в PNG (390dp xxhdpi) через
Robolectric+Roborazzi, recordRoborazziDebug зелёный. Основа автономного Fd-прохода:
экран → PNG → сравнение с веб-мобильной forbion. Роли добавляют тесты на свои экраны.
