Reduce relay rejection by adjusting session sync allowance

Decrease the client session sync allowance to improve relay handling within tolerance. This adjustment provides an additional block for mesh to notify the servicer about relays, helping to prevent relay rejection due to evidence sealing. Aim for better session rotation timing with the new configuration.
