Soft keyboards have no reliable Enter-to-send, so chat was unsendable on
mobile browsers. Add an optional themed Send button wired through
wireAgentChat (Enter-to-send kept for desktop), applied to the Companion
rail, Yerin, and Little Blue composers. Blackflame-styled, flex-row layout.

- .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
