Port errata-form page JavaScript files to TypeScript (CORE-1205) (#2774)

* Convert errata-form page JavaScript files to TypeScript

- Added comprehensive type definitions for all components
- Converted 10 JavaScript files to TypeScript (.js -> .tsx/.ts)
- Added proper typing for React components, hooks, and event handlers
- Used inline type definitions and avoided 'any' type per guidelines
- Maintained existing functionality while improving type safety

Files converted:
- errata-form.js -> errata-form.tsx
- errata-form-context.js -> errata-form-context.tsx
- form/form.js -> form/form.tsx
- form/ErrorSourceSelector.js -> form/ErrorSourceSelector.tsx
- form/ErrorTypeSelector.js -> form/ErrorTypeSelector.tsx
- form/InvalidMessage.js -> form/InvalidMessage.tsx
- form/FileUploader.js -> form/FileUploader.tsx
- form/ErrorLocationSelector/*.js -> form/ErrorLocationSelector/*.tsx
