fix: Input text fields no longer have transparent backgrounds after tailwind update (#2809)

## Description:

Woah 🚨🚨 massive PR alert!!! Kidding, this is a really small fix that
adds back the white background on text input fields since (I believe)
the tailwind updates made recently reset the styles here. This just adds
it back via CSS.
