Загрузочное меню ISO было оформлено в стиле Virtuality

- графическая тема GRUB (фон, подсветка выбранного пункта, полоса
  автозапуска) в image/grub, подключается в build-iso.sh; при отсутствии
  модулей GRUB меню остаётся текстовым;
- пункты меню переведены: «Установить Virtuality X.Y.Z», «Загрузить
  с другого диска», «Настройки UEFI», «Проверить память»;
- tests/render_html.mjs рендерит HTML в PNG (для фона темы).

+# Тема загрузочного меню
+
+`theme.txt` — тема GRUB (gfxmenu) для установочного ISO, `background.png` — фон 1024×768,
+`select_*.png` — подсветка выбранного пункта.
+
+Фон рендерится из `background.html` (тот же стиль, что у страницы входа панели):
+
+```bash
+NODE_PATH=$(npm root -g) node tests/render_html.mjs image/grub/background.html image/grub/background.png 1024 768
+```
+
+Пиксмапы подсветки — однотонные RGBA 6×6 (110, 96, 255, 150).
