What

Fixes missing participant join and leave system messages when the client device clock differs from the ACS SDK clock. The recovery query now uses the participant event timestamp instead of client device time.

Why

Client devices with clock skew are not seeing participant joined system message in the chat thread
Related to this IcM https://portal.microsofticm.com/imp/v5/incidents/details/21000001135358/summary about missing typing indicators also caused by clock skew

How Tested

Tested in locally by applying a 45 second clock skew to receiving device

Before with release validation app when remote participant joins chat thread:

After with local deploy when remote participant joins chat thread:
