Laya render image

[lpullela]

Overview

In this PR, I added lower resolution background images for faster load times.

Feedback Request (Optional)

we are supposed to come up with the optimal trade off between rendering time and quality. I think the image looks fine even though it's super low resolution.

Future Possibilities (Optional)

we can have a light mode/dark mode parameter?

Validation (Optional)

1. Download this branch.
2. Run the project.
3. Go to the log in page and see if the image a) renders quickly, and b) looks nice enough

Closes #4

[lpullela]

there are problems running the mutation coverage in the front end directory in the main branch (source code). this bug is the reason for the axios errors. we can make a new branch and try to fix this.
