add metrics.system.network.io prefixed field to semconv scenarios

rmyz · rmyz · commit 25eac362a832 · 2026-03-27T12:59:20.000+01:00
The Lens formulas for semconv network KPIs use the metrics.* prefixed
field. Without it, TX/RX tiles would show blank — same pattern already
applied for CPU, memory, and disk metrics.
