Refactor error logging across the application to use a centralized logger

- Introduced a new logger utility (`logError`) to standardize error logging.
- Replaced all instances of `console.error` with `logError` in various API routes and libraries.
- Enhanced error logging to sanitize sensitive information, particularly for Prisma and Stripe errors.
- Ensured consistent error handling and logging practices throughout the codebase.
