feat(ui): blackflame theming pass — edit toggle, md tables, back button, Little Blue action cards

- markdown_editor Edit toggle uses themed ghost button
- .md-preview gets full blackflame styling incl. tables (migrated BookStack tables now render as tables)
- reusable back button on page/reference/project/resource reading views
- Little Blue actions regrouped into themed cards, pairing Start/Stop per guest
