feat(server): enhance skill management and error handling

- Added middleware to handle invalid JSON body errors, returning a 400 status with a descriptive message.
- Introduced functions to normalize and filter mode tags for user permissions, improving access control for skills based on user roles.
- Updated API endpoints to incorporate mode tag filtering, ensuring users can only access skills they are permitted to view.
- Implemented a new endpoint for updating skill tags, with permission checks for non-admin users.
- Enhanced the frontend with updated styles and layout adjustments for better user experience.
