[Tech Enhancement] Implement standard sizes on `Text` and `Input` components

### Verified issue does not already exist?

- [X] I have searched and found no existing issue
- [X] I will be providing steps how to reproduce the bug (in most cases this will also mean uploading a demo budget file)

### What happened?

Currently, there is no standard sizes for texts and inputs across the app. This enhancement is to extend the `Text` and `Input` components to have a size prop which accepts some standard size values:

- small
- medium
- large
- extra-large

These standard sizes should vary between screen sizes e.g. different set of width and height for desktop, tablet, mobile

This change should help make all the texts and inputs more uniform in sizes throughout the app
