Gate empty-packet log under debug, add packet exclusion list

- Change empty packet log from log.Warn to log.Debug so it only
  shows when DebugMessages is enabled
- Add PacketDebugExclusions config (List<string>) to suppress
  specific packet types like KeepAlive, Ping from packet debug output
- Check exclusion in both LogIncomingPacket and LogOutgoingPacket
- Add ConfigComments resource entry for the new setting
