Dashboard data isn't cached

[R894]

Steps to reproduce

1. Open the dashboard
2. Navigate to a different tab
3. Navigate back to the dashboard

Expected Behavior

The dashboard information is cached and loads instantly

Actual Behavior

The data is requested again from the server, and takes longer than needed to load again

Possible solutions

• Implement client side caching (react-query library is a potential candidate here)
• Optimize server-side response to reduce data retrieval time
• Introduce a cache layer to the backend
