Fixes the Vercel deployment error "useSearchParams() should be wrapped
in a suspense boundary". Extracted the client component that uses
useSearchParams into a separate ArenaContent component and wrapped it
with React Suspense in the page component.

…ages

- Make Supabase browser client a singleton to prevent AbortError from
  multiple auth listeners being created
- Show actual error message when post publishing fails

The auth callback was creating cookies via cookies().set() but then
returning a new NextResponse.redirect() that didn't include them.
Now cookies are set directly on the response object that gets returned.
