feat: update Docker Compose, CI, and add runtime-base Dockerfile

Add jardata volume, CAMELEER_AUTH_TOKEN/CAMELEER3_SERVER_ENDPOINT/CLICKHOUSE_URL env vars to cameleer-saas, CAMELEER_AUTH_TOKEN to cameleer3-server, runtime-base Dockerfile for agent-instrumented customer apps, and expand CI surefire excludes for new integration test classes.
