Content Overflow in Event Details Section Affects Entire Page

[adimail]

Describe the bug
On the Events page, there are three main sections. The "Event Details" section lacks vertical scroll (overflow-y: auto). When the content in this section exceeds the visible area, it overflows and disrupts the layout of the entire page. Instead of making the whole page scrollable, only this section should scroll independently.

To Reproduce
Steps to reproduce the behavior:

1. Go to the Events page
2. Select or load an event with a long description/content
3. Observe how the "Event Details" section expands and pushes other sections
4. Try scrolling — the entire page scrolls instead of just the details section

---

Expected behavior
Only the "Event Details" section should have scroll enabled (overflow-y: auto) when content exceeds its max height. This will keep the layout clean and prevent disruption across the other sections.
