Implement retro-themed styling and classic pixelated icons for the archive browser when the "retro" theme is active. Changes include: - Adding CSS overrides for `[data-theme="retro"]` to style the archive browser container, tree nodes, and hover states. - Updating the JS preview script to dynamically append retro image icons (e.g., classic shell32/zipfldr icons) alongside SVGs. - Toggling visibility between SVG and retro image icons using CSS based on the active theme.
