refactor: Extract new function `show_preview_area` for the compose box. 

The code responsible for switching from edit mode to preview mode from
`compose_setup.js` is now extracted into a new function in `compose.js`,
to facilitate reuse.

This is a prep commit for introducing a hotkey to toggle between edit
and preview mode for the compose box.
