feat: enhance non-responsive content styles in default-base.css

- Reintroduced the .content--non-responsive class to maintain a minimum width for complex page templates.
- Updated styles for definition lists to ensure proper layout and responsiveness.
- Added specific input field max-widths to improve usability in non-responsive contexts.

This change aims to ensure that non-responsive layouts are styled correctly while maintaining usability across various input types. No further changes are pending for this task.
