`rt-justify` has been in the sanitiser's allowlist all along, and styles.css gives it `text-align:
justify` with `hyphens: auto` — hyphenation being what stops justified text opening rivers of white
space between words. Only the toolbar was missing it.
The four are now a list beside the toolbar rather than a ternary chain, and the comment says what it has
to match: ALIGN_CLASSES in the site's rich-text.ts. A fifth offered here would be stripped on save,
silently, leaving somebody pressing a button that appears to do nothing.
