App.toml cache size ignored

Medium Severity

The template adds ss-cache-size-bytes under [state-store], but node startup still builds StateStoreConfig via parseSSConfigs in app/seidb.go, which never reads state-store.ss-cache-size-bytes. Custom values in app.toml therefore never reach OpenDB, so operators cannot increase the Pebble block cache despite the new setting.
