fix(test): mock AnalyticsModule in MCP integration test

The AnalyticsModule's controller and services depend on ConfigService
and OpenSearchClient which aren't available in the MCP test module.
Use overrideModule to replace the entire AnalyticsModule with mocks.
Also add explicit ConfigModule import to AnalyticsModule.
