Left-align tables, drop the box around the support areas list

- Sphinx centres tables without :align:, and Furo keeps that, unlike
  sphinx_rtd_theme. Align them left like the rest of the text.
- A titled `.. contents::` renders as a teal topic box with a pencil
  icon in Furo. Use a plain sentence before the list instead.
