TekH f1c8e223dd Refactor ComposeSignaturePreviewPng to return Stream ...

Updated the `ComposeSignaturePreviewPng` method in the `IPdfPageImageRenderer` interface to return a `Stream` instead of a `byte[]` for improved memory efficiency when handling large image data.

- Added `ComposeSignaturePreviewPngBytes` extension method to convert the `Stream` to a `byte[]` for backward compatibility.
- Updated `PdfPageImageRenderer` to return a `Stream` and adjusted its internal logic to reset the `MemoryStream` position before returning.
- Modified `DevSignatureInkController` to use the `Stream`-based implementation for HTTP responses.
- Made minor formatting adjustments in `PdfPageImageRenderer`.

These changes optimize memory usage while maintaining compatibility with existing workflows that require `byte[]`.
