refactor(icons): drop all-the-icons, nerd-icons drives everything

nerd-icons already rendered every icon in the config (dashboard, dirvish, ibuffer, completion). all-the-icons survived only as scaffolding: a font-install helper, the all-the-icons-nerd-fonts bridge, and a terminal-blanking advice block the nerd-icons one beside it already duplicated. I removed all of it and pointed the font-install helper at nerd-icons (Symbols Nerd Font Mono), keeping the auto-install-on-first-GUI-frame convenience. I updated the font-config tests to the renamed helper.
