Improve the Functionality of the Discussion Section

[Nishitbaria]

The Discussion section at https://electivehub.onrender.com/discussion currently lacks both in terms of styling and functionality. This issue is created to address the visual and user experience aspects of the Discussion section.

• Usability: Users may find it challenging to engage in discussions due to the suboptimal layout and design.
• Functionality: The Discussion section may lack essential features like sorting options, user avatars, proper alignment, and visual cues for better user engagement.
