feat: Adds the ability to resize the editor (#13916)

# Pull Request Template

## Description

This PR adds support for resizing the reply editor up to nearly half the
screen height. It also deprecates the old modal-based pop-out reply box,
clicking the same button now expands the editor inline. Users can adjust
the height using the slider or the expand button.
