Preserve text when the clipboard also contains one image.

shouldUploadFilesOnly returns true for empty HTML without checking text/plain. It also ignores text nodes after an image because childElementCount counts only elements. onCapturePaste then uploads the files and returns before calling onPaste, so the text is lost.

Pass text to the helper and require both plain text and parsed HTML text content to be empty before selecting the file-only path.

In `@packages/fluent-editor/src/config/paste-image.ts` around lines 27 - 31,
Update shouldUploadFilesOnly to accept the plain-text clipboard value and select
the file-only path only when both text and parsed HTML textContent are empty;
account for text nodes alongside a single IMG element. Update onCapturePaste to
pass text into the helper, preserving the existing upload flow only for
genuinely image-only clipboard content.
