EnvelopeGenerator/EnvelopeGenerator.Server/EnvelopeGenerator.Server.Client/Pages/EnvelopeSenderPage.razor
TekH b2c245d6bd Optimize navigation by disabling force page reloads 
Updated `Navigation.NavigateTo` calls across multiple files to set `forceLoad` to `false`, preventing unnecessary full page reloads.

- **LanguageControls.razor**: Prevent full reload when switching languages.
- **EnvelopeSenderPage.razor**: Avoid reload during logout navigation.
- **LoginReceiverPage.razor**: Skip reload after successful envelope receiver login.
- **LoginSenderPage.razor**: Prevent reload after successful sender login.

These changes improve performance and enhance user experience by enabling smoother page transitions.
