refactor: tui-rs 0.11.0 refactor

[ClementTsang]

Description

A description of the change and what it does. If relevant, please provide screenshots of what results from the change:

Refactors tui-rs usage to the new 0.11.0 release. This release also fixes the highlighting bug from #249, and now, expanding a widget no longer overrides the widget title colour.

This commit also introduces #255, but that seems to be easy to bandaid so hopefully it will get fixed soon?
