feat(e2e): add chain initialization and deployment scripts

Add the core chain deployment pipeline for Kind-based e2e tests:
- init-chain.sh: Multi-validator genesis initialization (keys, gentx, SP genesis, config patches)
- deploy.sh: Full K8s deployment orchestrator (init job, config extraction, StatefulSet creation)
- genesis-init-job.yaml: K8s Job manifest for running chain init in-cluster
- validator-services.yaml: Headless + NodePort services for validator networking
