The owner wants LibreNMS-like 5-minute polling by default and the option
to poll a given device faster or slower. Devices gain poll_interval_s
(new migration; 0 means the default, otherwise 30 to 3600 s), settable in
the device edit dialog and through PUT /api/v1/devices/{slug}; the
poller picks it up on the next inventory refresh.
Everything that assumed one-minute samples now follows the device's
interval: graph and p95 rate windows are at least two polls, the max
series uses irate, the up-series lookback, the no_data warning, the
"unheard of for three polls" fallback and the rollup's thin-window check.
interface_errors widens to 10 m. profiletest keeps 60 s because the
expect budgets are keyed by the 1m group. Recorded as DEVIATIONS 49.
