Improve UX and update UI color scheme to blue

- Add @onblur and @onmousedown handlers to input/button for better focus and click behavior
- Change download button disabling logic to only depend on processing state
- Update progress bars, status, and card colors from green to blue
- Add .output-message CSS class for blue-themed output messages
- Adjust pulse animation to use blue tones
- Add OnInputBlur and PreventDefault methods for improved input/button interaction
