Initial commit: Infrastructure host tracking app

Fastify + node:sqlite single-process app with vanilla JS UI for
looking up hosts by hardware ID, hostname, or asset ID. Includes
per-host network interface tracking, sites/rooms/server-types CRUD,
Docker packaging, and a Gitea Actions workflow that runs tests then
builds and pushes to gitea.thewrightserver.net/josh/infrastructure.
