On the live instance the hourly refresh took 3 min 8 s, averaging a week of
raw temp_c samples each time. The hourly averages are now kept in memory.
The first refresh after startup reads the whole window. Each later one reads
raw samples from the start of the hour the last read ended in, so the hour
that was still filling is read again whole. merge_hours folds the new rows
in and drops hours older than the window.

Rollups exist only for hours older than the raw window (7 days by default),
so the first deploy read an empty week and judged nothing. refresh now
averages the raw samples by the hour and adds any rolled-up hours in the
window. Sensors are named from plugin_metric_latest, so each series is read
through its index instead of a pattern over every host_agent row. An
integration test covers both halves against Postgres.

A board's spare thermistor inputs report whatever an open input reads, and
the value rule from #5759 only catches the impossible ones. Once an hour,
sensors.refresh judges each sensor against the host's CPU (Package id N,
Tctl/Tdie/TccdN, PECI Agent N) over a week of hourly averages. A sensor is
ruled out if it falls as the CPU warms (r <= -0.5) or holds within 0.5 °C
while the CPU moved 10 °C or more. A judgment needs at least 72 shared hours.
The host temperature leaves judged sensors out at ingest. The host page
lists them under "Not counted", with each reason given once.
