forgectrl pinned at the status-page sys block; panel-serves reads it

The pin picks up /status carrying CPU and memory utilization (sys:
cpu_pct over the interval since the previous read, mem_pct from
MemTotal against MemAvailable) with the panel rows under the board
temperatures. forgectrl.panel-serves now re-reads /status after a
beat and asserts both percents are numbers in range, so the catalog
exercises the new telemetry on the bench.
