Refactor and optimize envelope handling

Refactored `ReadDocumentDetailsQueryHandler` to remove AutoMapper, improving performance by manually selecting necessary data. Simplified `SenderEditorPage.razor` by removing bootstrap logic and updating the UI for a more compact design. Streamlined envelope creation in `SenderPage.razor` by eliminating the bootstrap token. Updated styles in `envelope-viewer.css` for better alignment and readability.
