Initial implementation of Bluetooth toy control app

Next.js app with a browser-side buttplug/buttplug-wasm control layer
(server never touches real-time device commands), SQLite storage via
Drizzle, single-secret auth, recordings/replay with device remapping,
a usage stats dashboard, Docker deployment, and Gitea CI.
