fix(pages): make install-channel command box scrollable - #912

LGTM

LGTM! Clean fix for a real UX annoyance — nice work.

A couple of ideas for a follow-up PR if you're interested:

1. Consider using <div> instead of <span> — overflow-x: auto technically only works on block-level elements. It works here because the span is a direct flex child, but it's a bit fragile. If someone later wraps it or changes the parent layout, scrolling could silently break. Swapping to a <div> (or adding explicit display: block) would make the intent clearer.

2. Scroll hint with a right-edge gradient — Now that the ellipsis is gone, there's no visual cue that the command extends beyond the visible area (especially on macOS where the scrollbar auto-hides). A subtle fade using something like mask-image: linear-gradient(to right, black 90%, transparent) that disappears once scrolled to the end could help discoverability.

Neither of these is blocking — merging as-is. Thanks for the contribution!
