PR Summary

Low Risk
Test and deployment-config parity only; no runtime behavior changes beyond aligning one numeric literal with integer JSON.

Overview
Adds a CI test that the consolidated jsonnet build’s applicative defaults stay aligned with the committed app_configs/*.json layer (non-overridable deployment values).

The check evaluates build('consolidated', testing overrides), round-trips through SequencerNodeConfig and config_to_preset, merges all base app_configs JSON (skipping replacer_*), and compares keys while excluding overridable keys (KEYS_TO_BE_REPLACED), secrets, config pointers, and components.*. Supporting pieces: test_applicative_matches_app_configs in jsonnet.rs, is_path_prefix for dotted-key subtree matching, and BASE_APP_CONFIGS_DIR_PATH made pub(crate) for the merger.

l1_events_scraper_config.l1_block_time_seconds is normalized from 12.0 to 12 in jsonnet and the matching app config JSON so values match integer serialization from the config dump.
