refactor: improve form validation in CodexConfigEditor using HTML5 validation API

- Replace custom error state with native HTML5 form validation
- Add useRef hooks for input field validation management
- Add pattern attributes to enforce non-empty input validation
- Leverage browser's built-in validation UI for better UX
- Extract closeTemplateModal function for consistent modal closing
