ux: render the logo.ans ANSI-art splash in the loading overlay

_load_logo() reads logo.ans (repo root) once, strips the cursor show/hide escapes
so Rich sees only SGR, and parses it with Text.from_ansi (no_wrap). LoadingScreen
renders it above the title, centered in the box; missing/unreadable logo degrades
to no splash art. Verified: 33x60 art mounts in the modal and renders in 256-color.
