PR Summary

Low Risk
Deployment config deduplication with per-env cache sizes unchanged in intent; no application or auth logic changes.

Overview
Introduces a shared hybrid committer service overlay at configs/overlays/hybrid/common/services/committer.yaml and wires mainnet, sepolia-alpha, and sepolia-integration to it via include, instead of duplicating the same service definition in each environment.

The common file holds shared sequencer settings (config list, verify_state_diff_hash, batcher/committer URLs and ports) and the ClusterIP service on port 55013. Each environment overlay now only overrides committer_config.storage_config.cache_size (50M on mainnet, 10M on the Sepolia overlays).
