Implemented the Unexpected Naviagtion and Misaligned Text

[akhileshdasari2004]

1. Unexpected Navigation:

   • Navigation to "output" only occurs after a successful API response in sendToBackend.
   • Prevented abrupt redirection by handling errors properly.

2. Misaligned Text:

   • Ensured proper alignment of text by adjusting text-center and justify-center in the question generation section.
   • Fixed text spacing issues in <div className="text-center mt-[-8px] mx-1">.
   • Applied consistent padding and margins for text areas and buttons.
