fix: console errors in SampleSheetStep component

## Description

The `SampleSheetStep` component produces two React console errors:

1. **`isDragActive` prop on a DOM element** — React does not recognize the `isDragActive` prop on a DOM element. It should either be removed from the DOM element or spelled as lowercase `isdragactive` if intended as a custom attribute.

2. **`error` attribute receives `false`** — A non-boolean attribute `error` receives `false`. It should either be passed as a string (`error="false"`) or conditionally omitted (`error={condition ? value : undefined}`).

## Component path

`app/components/Entity/components/ConfigureWorkflowInputs/components/Main/components/Stepper/components/Step/SampleSheetStep/sampleSheetStep.tsx`

Open app/components/Entity/components/ConfigureWorkflowInputs/components/Main/components/Stepper/components/Step/SampleSheetStep/sampleSheetStep.tsx and inspect how isDragActive and error are passed to DOM elements. Reproduce the SampleSheetStep console output, then update the prop handling so both React warnings are gone and verify the component no longer emits these errors.
