Implemented 'process_ae_obj__activity_log_props' with robust timestamp fallbacks.
Refactored 'qry__jitsi_report' to follow the Frontier module pattern, ensuring consistent V3 search and local cache synchronization.
- Explicitly added the 'x-account-id' header to resolve HTTP 403 error when fetching Jitsi activity logs.
- Ensures the server-side scope check passes for these report requests.
- Added Array.isArray check to prevent 'not iterable' error on API failure responses.
- Restored params_json to narrow the activity_log query and prevent potential timeouts.
- Cleaned up minor whitespace in sort logic.
