Improvise Events Page

[SatyaRajAwasth1]

The events.html page should be updated to:

• Make the event section easier to use on our website.
• At the top, talk briefly about our events and pin important ones.
• Show upcoming events next, and then other events below.
• Each event Card will have a banner, title, date, venue, a short description, and Know More link.(similar as in home page...)
• When you click on "Know more," you'll see all the details about that event in a separate page.
• The event details should be fetched from a JSON file. (Upcoming and past should be calculated automatically according to date.)
• This change will help people find and understand our events better, so they can join in more easily.
