Subject: [PATCH] Add "Cancel" button and navigation to sender page

Added the `NavigationManager` service injection to the
`EnvelopeSenderEditorPage.razor` file to enable navigation.
Introduced a "Cancel" button in the toolbar, styled with
`pdf-toolbar__btn pdf-toolbar__btn--reset`, which triggers
the `Cancel` method on click. The `Cancel` method navigates
the user to the `/sender` route, improving the user experience
by providing a clear way to cancel the current operation.
