Make the landing page faster to load

[code-geek]

Description

Right now since we load all the data all at once, the landing page has become very slow (over 2 seconds to load every single time).

The goal of this issue is to make the landing page faster.

Implementation Considerations

• Django ORM select_related etc can be implemented to fetch data more judiciously
• Lazy load data on the homepage with infinite scroll that calls API (pagination on the server side instead of pagination on the client side)
• Caching (redis/memcached)
• Database indexes
• How does this affect Universal Search

Deliverable

• A faster landing page
