Device Sessions: document the columns the panel actually shows
Regenerated from docs/userguide.md. The Device Sessions section still
described the pre-1.2.2 panel: it listed columns that were never
populated (hostname, user) and omitted protocol, client IP and the
byte counters. Now names the real columns and explains that the User
column reflects the account's current name.
Cross-page links and screenshots regenerate unchanged.
Illustrate the guide with 21 screenshots, and sync content since the last pass
The guide had been text-only. It now carries screenshots of sign-in, the
hierarchy sidebar and its + menu, the dashboard, SNMP targets, the canvas, the
node context menu, the View menu, area clouds, node and link details, the LSDB
browser, the routing table, single points of failure, a computed path and its
hop table, simulation impact, the time-travel bar, alert rules, the SSH
terminal and system settings.
They live in this repo at images/ and are referenced relatively, the same path
the source guide uses, so the in-app guide and the repo render them from their
own copies without any per-target rewriting.
Also picked up from docs/userguide.md since the last sync: the GRE-vs-SNMP
comparison and why polled LSA header fields are deliberately omitted, the LSDB
browser being OSPF-only, IS-IS route labelling by level (I L2 across levels,
I IA for leaked prefixes), the RIB's Route column and per-hop proven/modelled
marks, the ECMP xN badge, the IGP Prefixes Area column and unique-prefix count,
and the "Add Routing Domain" menu label the screenshot showed was wrong.
