✨ feat(input): enhance input component with custom onChange handler

- modify InputProps to omit and redefine onChange with value-first parameters
- add handleInput method to extract value and pass to custom onChange
- maintain backward compatibility by calling original onInput if provided
- update props interface to support new onChange signature (value: string, event: any) => void
