By defining listen on separate ip you exclude it from matching 
on servers with listen *, very much like what happens with two 
separate listening sockets.

I.e. with your config only "phpmyadmin" will respond on 
192.168.1.1:80, and only "bots" will respond on 127.0.0.1:80.

If you want www.site.com to handle requests on 192.168.1.1:80 as 
well - you have to explicitly include this listen into 
www.site.com server, i.e. use

    server {
        listen        *:80;
        listen        192.168.1.1:80;
        server_name   www.site.com;
    }

The same applies to other servers/listens.
