fix(web): fully remove withPayload + admin routes from prod

withPayload crashes ALL routes with React #130 in standalone
output — even with admin page replaced by redirect. The wrapper
injects a client-side ConfigProvider that fails hydration.

Removed: withPayload wrapper, entire (payload) route group.
Kept: payload.config.ts, migrations, blog/changelog server-side
queries with graceful DB fallback.

Payload admin runs on local dev only (add withPayload back in
next.config when running pnpm dev). Production content via
static TSX pages or future API-based publishing.
