admin 34d83f5a02 feat(disk-health): poll hourly, not 6-hourly — measured, not assumed ...

Part 4 was gated on a measurement. On demo-hp (Tier 0) the controller's real
/disks fetch — fetchDisks, the same path the check uses, not the 60s card
cache — costs min 0.805s / median 0.821s / max 0.841s over 10 calls, all HTTP
200, across 3 physical disk rows (2 distinct devices). Median is 6x under the
5s bar, so the <5s branch applies and the interval drops 6h -> 1h.

Why it matters: the one real failing drive's benign excursion lasted about ONE
HOUR and cleared completely. A 6-hourly sampler can land either side of an
excursion like that, see nothing, and then catch the terminal run half a day
late. The smartd history that produced the whole analysis sampled every 30
minutes and only just resolved the shape.
