ci: switch from GitLab CI to Gitea Actions, fix Dockerfile.backend

- Replace .gitlab-ci.yml with .gitea/workflows/deploy.yml
- Fix Dockerfile.backend: add scan_processor.py and searcher_v3.py to
  COPY command (they were missing, would cause runtime ImportError)
- Update docker-compose.yml comment to reference Gitea workflow

+# PREREQUISITES (one-time setup — see README for full instructions):
+#
+#   1. Add the act_runner service to your Gitea Portainer stack.
+#
+#   2. Pre-create the runner config file on the host:
+#      /srv/docker/traefik/stacks/gitea/volumes/act_runner/config.yaml
+#      (see content in the README / deployment docs)
+#
+#   3. Start the runner, then grab the registration token from:
+#      Gitea → Site Administration → Runners → Create Runner
+#      Add ACT_RUNNER_TOKEN to Portainer stack environment variables.
+#
+#   4. Give the runner access to Docker (socket mounted via config.yaml).
+#
+# PIPELINE BEHAVIOUR:
+#   • Triggers on every push to the default branch (main).
+#   • Builds both Docker images on the server (no registry needed).
+#   • Brings the app up with docker compose; only changed services restart.
+#   • If the build fails the old containers keep running — no downtime.
+#   • Prunes dangling images after a successful deploy.
