fix(admin-web): use dedicated trading client with correct base URL

Trading API was incorrectly routed through mining-admin baseURL in production,
causing 404 errors. Created independent tradingClient with /api/trading baseURL
to properly route requests through Next.js rewrites to Kong -> trading-service.
