fix: one setup decision for line mode and screen

Line mode finds mounted cards, shows its menu and names the folder for a
pack, asks the folder instead of taking a default, and lists setups in the
screen's order. Devices have one spelling each, matched without case,
spaces or punctuation, and a device several systems run lists them all.
--tui --dest reads a card as --plain does. Card boundaries read every
parent up to a mount point from mountinfo. --offline with --yes counts the
files it leaves out as pending, never as failed. The P3 points of
code_audit_15 and tui_audit_8 follow.
