Add Maria WhatsApp+RAG bridge as a service (LXC 171)

Move the /tmp prototype (Baileys bridge + RAG consumer) into git as a
proper sibling project to discord-bridge/: own systemd --user units
(whatsapp bridge, rag consumer, dashboard, periodic Drive sync timer),
a filesystem document store with a stdlib control dashboard (start/
stop/restart, document CRUD, reindex, Google Drive sync via rclone),
and an idempotent ops/install.sh following the same conventions.
