Refactored routing logic in `SenderEditorPage.razor` and `EnvelopeSenderEditorPage.razor`:
- Changed the route in `SenderEditorPage.razor` from `/sender/editor2` to `/sender/editor`.
- Updated `EnvelopeSenderEditorPage.razor` to use `/sender/editor_legacy` instead of `/sender/editor`.
- Adjusted `NavigationManager.NavigateTo` calls to reflect the new routes.
These changes separate the functionality of the two pages and clarify their respective roles.
