fix: use fixed height for bottom bar (#23)

Closes: WORLD-1013

## Overview
Inconsistent bottom bar UI when collapsed in different screens. This is caused by react-resizable-panels using only percentage values instead of pixels.

## Brief Changelog
- Show fixed height "bar" when panel is collapsed. This element is separate from the original panel contents.
