[V2] feat(sign): add automatic white background removal for signature images (#5210)
# Description of Changes



This pull request adds a new feature that allows users to automatically
remove the white background from uploaded signature images, making them
transparent. The changes include UI improvements for image uploading,
new image processing utilities, and updates to translation files for
better user feedback.

### Image Upload & Processing Enhancements

* Added a `removeWhiteBackground` utility function in
`imageTransparency.ts` to process images and remove white backgrounds,
with options for automatic corner color detection and tolerance
settings.
* Updated the `ImageUploader` component to support background removal,
including a checkbox for toggling the feature, processing state
feedback, and integration with the new utility

### Signature Tool Integration

* Modified `SignSettings.tsx` to enable the background removal feature
for signature images, handle processed image data, and ensure signature
placement logic works seamlessly with the new feature.

### UI & Localization Updates

* Added new translation strings for background removal and image
processing feedback in the English locale file.
