Refresh rate is honoured exactly everywhere: no list floor, sampler up to 10 s, server caches reduced to coalescing only

-          Dashboard charts, the Processes tab, disk activity and the machine list all poll at this rate. The dashboard's sampler on each machine follows it too (fastest 100 ms, slowest 2 s; charts keep 300 points, so the window is 300 × rate).
-          Lists that shell out on the host — services, cron, updates — never go faster than {fmtMs(LIST_FLOOR)}.
+          Every page polls at exactly this rate: dashboard, processes, disks, services, cron, updates, machines. The sampler on each machine follows it too, so charts keep 300 points and cover 300 × rate.
+          Fast rates cost CPU on the host, especially on the list pages, which run commands to refresh. Nothing is throttled behind your back.
