chore(editor): Tweak restore modal dialog and chat message (no-changelog)

[Tuukkaa]

Summary

Updates the restore version modal UI and messaging:

• Copy improvements: Simplified the restore modal description text to be more concise and user-focused. The new messaging emphasizes that the current version will be saved rather than being replaced.
• Layout adjustment: Removed horizontal padding from the restore message container to improve alignment with the overall dialog design.
