PR Summary

Medium Risk
Upgrades production sync/RPC node binaries; schema is unchanged but rollout timing and chart release (0.1.51) affect live infra.

Overview
Bumps the Abstract external node from v33.1.0 to stable v34.0.1 across Helm and local Docker, matching Matter Labs’ v34 rollout.

The abstract-node chart is released as 0.1.51 with appVersion v34.0.1; default image.tag and digest point at the multi-arch Docker Hub index sha256:ba3d1030…. Docker Compose defaults for generate-secrets and external-node use the same version and digest, and new mainnet/testnet .env files pin those values for each network (same approach as prior upgrade PRs). No chart logic or migrations change—this is a version pin refresh only.
