Temporary slice events to save over-rendering, split events into curr…

[alexzhang1618]

Description

• So I noticed on prod that there are way more events and our current display is rendering them all, making the page really laggy.
• As a temporary fix, I'm slicing it to a max of 20 events on the page
• I also added some extra code to split events into live, past, and future, which will be useful down the line
• This can be considered some scaffolding code for the dashboard page down the line.
