Function file_row 

pub fn file_row(file: &FileChange) -> ListItem

Format a changed file as a list row: a colored status marker in the icon gutter (see [status_icon]) followed by the path. The marker replaces the old single-letter text badge — the same A/M/D/… letters, but baked from SVG so they stay crisp at any DPI and legible on the navy selection band.
