feat(api): enhance backend API configuration and routing for multi-domain support

- Updated `next.config.mjs` to implement host-based routing for two domains, allowing seamless API proxying to the appropriate backend based on the host.
- Refactored backend API base URL logic in `config.ts` to dynamically determine the correct URL based on the deployment environment, supporting both production and test setups.
- Modified `CreateCompany` form to validate website input with a regex pattern and changed input type to text for better user experience.
