This commit adds the server-side handler for the BlocksByRange protocol, integrates it into the SyncService, and enhances the backfill synchronization with range-based fetching. It also includes a strict SSZ validation fix for fixed-size containers to ensure malformed oversized payloads are correctly rejected.
This commit addresses multiple linting violations (E501 line length), fixes missing imports in head_sync.py and test helpers, and restores/enhances test coverage for malformed SSZ payloads in the request/response layer.
