`getDiskHealthBreakdown` carried its own hardcoded ladder (HDD ≤45
normal, ≤55 warning) that was much stricter than the configurable
defaults consumed by `getTempColor` via `useDiskTempThresholds`
(HDD warn 60, hot 65). HDDs at 48 °C therefore rendered a green
"Healthy 48°C" badge on the card but were tallied as "warning" in
the top-of-page "X normal, Y warning, Z critical" summary, leaving
the user with the misleading "6 normal, 5 warning" line.
Use the same threshold map as the per-disk badge so the colour and
the count are always consistent, and so Settings → Health Monitor
Thresholds → Disk temperature actually applies to the breakdown.
