fix(editor): preserve image styles when replacing an image

[danilowoz]

When replacing a selected image via the uploadImage command, carry over the existing image node's attributes (style/border-radius, width, height, alignment, href, alt) instead of resetting them to defaults. Only the src is overridden with the new blob URL. Paste/drop/slash-insert of a brand-new image (no image selected) is unaffected.

Adds a focused upload-flow.spec.ts covering both the replace (attrs preserved) and fresh-insert (no carry-over) paths.

Summary by cubic

Preserves existing image styling and metadata when replacing a selected image via upload; only the image source changes and paste/drop/slash-insert of new images is unchanged. Adds a changeset for a minor @react-email/editor release.

• Bug Fixes

  • Preserve style, width, height, alignment, href, and alt when replacing a selected image; only src updates (blob → uploaded URL).
  • Detect selected image with NodeSelection and pass its attrs to setImage; tests cover replace vs fresh insert in upload-flow.spec.ts.

• Refactors

  • Removed unnecessary comments in upload-flow.ts.

<sub>Requires human review: Changes affect core editor logic for image upload/replacement, including state management via NodeSelection. A bug here could corrupt user content by incorrectly applying attributes. This requires domain knowledge of the editor's attribute handling and should be reviewed by a human.
