Replace the react-swipy implementation with something smoother

[Pjaerr]

I have noticed that using the react-swipy library for the card swiping can result in jankiness when swiping fast on mobile. This could potentially be replaced with something that is smoother.

The implementation is done within /frontend/src/components/CardContainer/CardContainer.js

Upon testing, it seems that the implementation is smooth on the first use, but if you go back and switch to another category it gets progressively slower. This may be due to not cleaning up the Swipeable component.
