Refactor code for improved readability and consistency across multiple files

- Updated formatting in `drawing_toolbar.dart` for better readability, including breaking long lines and ensuring consistent indentation.
- Enhanced the `recipient_selector_sheet.dart` by adjusting line breaks and improving the layout of text styles.
- Refactored `sar_update_sheet.dart` to improve readability, including restructuring widget layouts and ensuring consistent formatting.
- Cleaned up imports and removed unnecessary lines in `widget_test.dart`.
