Pull request overview

This PR prevents the runtime-rule boot override resolver from touching storage when the receiver-runtime-rule module is not enabled, avoiding unnecessary DAO reads on MAL/LAL static rule load paths. It also hardens BanyanDB management-schema access to fail with a checked exception instead of an NPE, and introduces a no-op SessionCacheCallback for multi-write scenarios.

Changes:

• Short-circuit DbOverrideRuntimeRuleResolver.loadAll(...) when receiver-runtime-rule is disabled to avoid any storage/DAO access.
• Add requireManagementSchema(...) to BanyanDBStorageClient to throw IOException when management metadata isn’t registered yet (instead of NPE).
• Add SessionCacheCallback.NOOP for callers that must suppress cache updates (e.g., secondary backend in multi-write).
