Refactor analytics event handling and manager setup

Updated event handling in `analytics-provider.tsx` to return results, enhancing consistency. Added a new function `registerActiveServices` in `analytics-manager.ts` for initializing active services, streamlining provider setup. Clarified types for `AnalyticsProviderFactory` to accept optional configuration.
