Function DateInput

DateInput<Schema extends BaseSchema<any, any, any>>(
props: DateInputProps<Schema>,
): Element
A compound component for selecting a date using separate inputs for day, month, and year.
Type Parameters
- Schema extends BaseSchema<any, any, any>
Parameters
- props: DateInputProps<Schema>
  The component props.
Returns Element
The rendered date input wrapper.
Remarks
This component manages the state of three separate inputs and combines them into a single ISO date string (YYYY-MM-DD) in a hidden input for form submission. It uses a reducer to manage internal state and synchronizes with the value prop.
Example
```
import { DateInput, Day, MonthSelect, Year } from './date_input';

function BirthdayField() {
  return (
    <DateInput name="birthday" required>
      <Day placeholder="DD" />
      <MonthSelect />
      <Year placeholder="YYYY" />
    </DateInput>
  );
}
```
