fix: improve field sizing (#1486)

## Description

Allows for smaller field sizing in addition to improving our styling
when displaying labels on smaller fields.

This is the minimum currently supported field size until we perform a
more extensive refactor of our current drag and drop system.

## Changes Made

- Updated our minimum size constraints
- Attempted to add a general autosizing component for text and failed
- Updated styling in a bunch of places to use the css `clamp()` method
for dynamic sizing.
