chore: update wrangler configuration and optimize imports

- Changed the project name in `wrangler.jsonc` to `synapse-demo-dev` and added a production environment configuration with custom domain routing.
- Refactored imports in `payments-account.tsx` and `warm-storage-service.tsx` to streamline component usage by removing unnecessary imports, enhancing code clarity.

Example usage:
```ts twoslash
import { Card } from '@/components/ui/card';

<Card>
  <CardContent>Content goes here</CardContent>
</Card>
```
