Added status filtering for sessions and type/creation-time filtering for events

AI Impact Summary

The platform now enables more granular data retrieval by allowing sessions to be filtered by status and events to be filtered by type and creation time. This improves query precision for dashboards and analytics, reducing data noise and enabling targeted investigations. Backend and API teams should ensure the new query parameters are validated and indexed to avoid performance regressions; clients should be updated to surface these filters in UIs or API calls.
