chore(deps): Update dependencies and refactor API routes for improved error handling

- Updated various dependencies in package.json and pnpm-lock.yaml, including '@clerk/nextjs' to version 6.7.1 and several others for better performance and security.
- Refactored API routes to use Promise.resolve for context parameters, enhancing reliability in asynchronous contexts.
- Improved error handling in the dashboard and studies components, ensuring better user experience during data fetching.
- Removed unused favicon.ico file to clean up the project structure.
- Enhanced the dashboard components to utilize a new utility function for API URL fetching, promoting code reusability.
