fix: pass SEI_CHAIN_ID env var to sidecar containers

The sidecar needs SEI_CHAIN_ID to look up embedded genesis for well-known
chains when no S3 genesis source is configured. Without it, configure-genesis
fails with "no S3 params and SEI_CHAIN_ID is not set".

Added to both StatefulSet and pre-init Job sidecar containers.
