Move the init-container loader image build from cameleer-server CI into this repo so all sidecar/infra image builds (runtime-base, postgres, clickhouse, traefik, logto, and now runtime-loader) live in one place. The loader is consumed by cameleer-server's DockerRuntimeOrchestrator as a per-replica init container that fetches the tenant JAR from a signed URL into a named volume before the main container starts. Source + Dockerfile copied verbatim from cameleer-server@c2efb7fb (the image with the volume-permission fix). The published tag path is unchanged (gitea.siegeln.net/cameleer/cameleer-runtime-loader:latest), so running tenant servers continue pulling the same image. Build step matches the runtime-base/postgres/clickhouse/traefik pattern (unconditional rebuild on every push, sha + branch tags, --provenance=false for Gitea). cameleer-server will follow up with a commit removing its loader-build step and switching its LoaderHardeningIT to pull the published image instead of building from a local Dockerfile.
