* fix: let usage table expand to fill available width
The usage page was constrained to max-w-3xl while the leaderboard table
needs a 760px minimum for its 7 columns, so it always overflowed and
forced horizontal scrolling. Add an optional maxWidthClassName prop to
AppShell and widen the usage page to max-w-5xl so the table expands when
space allows, keeping overflow-x-auto as a narrow-screen fallback.

* refactor: use cn-merged className override on AppShell
Replace the single-purpose maxWidthClassName prop with a general
className prop merged via cn (twMerge), matching the shadcn pattern. This
lets callers override any of the content-container classes ad hoc rather
than adding a new prop per override. Usage page passes className=max-w-5xl.
