Fix session explosion: skip session_start for agent/netscan/ping endpoints

Browse Source 
Agent heartbeats (every 10s from 13 agents) were creating empty session files
because session_start() ran unconditionally. Over months this produced millions
of 0-byte files in the session directory, causing PHP session GC to hang and
making all browser API calls intermittently timeout (panels show offline/empty).
