Subject: [PATCH] Add Docker build and Gitea Actions CI for deployment

Multi-stage Alpine Dockerfile producing a standalone Next.js image
with the better-sqlite3 native addon included. Gitea workflow builds
on push to main and on v* tags, pushing to the Gitea registry using
the REGISTRY_URL variable and REGISTRY_TOKEN secret. Compose file
mounts ./data so alerts.db and settings.json persist across restarts.
