Added dependency injection for `AuthService`, `ReceiverAuthorizationService`, `PageDataService`, and `Logger` to enable their usage in the component. Introduced a "Submit" button in the UI to confirm the signing process and complete the workflow.
Implemented a `DxPopup` component to display a confirmation dialog when the "Submit" button is clicked. The popup includes a message about the successful signing of the document and asks the user to confirm whether to complete the process and log out.
Added state variables `_isLoggingOut` and `_submitConfirmVisible` to manage the popup visibility and logout process. Created `OpenSubmitConfirmPopup` to toggle the popup and `SubmitAndLogoutAsync` to handle the submission process, including logging out via `AuthService` and navigating to the login page.
Updated the `@code` block with the new state variables and methods for managing the submit and logout functionality.
