On unpause, toggle SNAPFLAG_SERVERCOUNT and set SNAPFLAG_RESET_ENTITIES.
In CL_ParseSnapshot, detect SERVERCOUNT toggle and hard-reset
cl.serverTimeDelta instead of letting CL_AdjustTimeDelta slowly drift.
During pause, the delta drifted because snapshots had frozen serverTime
while cls.realtime advanced. Without the hard reset, it took 1-2 seconds
of choppy interpolation to re-sync.
