refactor: streamline API calls and enhance configuration management

- Refactor multiple API routes to utilize a centralized configuration function for base URL and token management, improving code consistency and maintainability.
- Replace direct environment variable access with a unified config function in the `lib/api.ts` file.
- Remove redundant error handling and streamline response handling in various API endpoints.
- Delete unused job-related API routes and settings, simplifying the overall API structure.
