fix(cli install): pass missing verbose arg and use background-neutral styles

1. Pass required `verbose=not quiet` to run_build_ast_graph() — fixes CI
   failure where the argument was missing after the function signature changed.

2. Drop hardcoded blue/cyan foreground colors from questionary styles.
   Bold + underline without explicit fg works on both light AND dark terminal
   backgrounds; the previous blue/cyan palette was unreadable on dark themes.
