Fix multi-index FGAC routing and add bypass regression tests
SQL plugin routing fix: - RestUnifiedQueryAction.isAnalyticsIndex() now splits comma-separated index names and checks each independently. Routes to analytics engine only if ALL indices are composite. Previously, the joined string 'idx1,idx2' was looked up as a single index in cluster metadata, causing multi-index queries to fall through to the legacy pipeline. Regression tests: - testPPLMultiIndexDeniedWhenSecondIndexUnauthorized - testPPLMultiIndexDeniedWithBackticksAuthorizedFirst - testPPLMultiIndexDeniedWithUnauthorizedFirst - testPPLMultiIndexAllowedWhenAllAuthorized Also fixes plugin install order (composite-engine before backends).
