feat: support smaller field bounds (#1344)

Currently this won't always display super well since
our insertion solution isn't amazing but our current
minimum bounds within the UI are a bit large and can be
smaller.

This change makes it smaller and uses container queries to
support dynamically displaying labels based on the container
size.
