Add Server stats (CPU, RAM, Disk, System) to admin Infra page

Browse Source 
First row shows host-level stats from /proc: CPU model, cores, load
average with charge %, RAM total/used/available with usage %, disk
total/used/free with usage %, hostname, OS and uptime. All color-coded
green <70%, yellow <90%, red >=90%.
