Add bulk recheck and auto-refresh to the IPs dashboard page

"Перепроверить выбранные" joins the existing "Удалить выбранные" / "Очистить
всё" bulk actions, using the checked-row selection the same way delete
already does — no control-api changes needed, since forcing a recheck of a
batch of addresses (new, finished, or already-queued, skipping anything
mid-check) is exactly what POST /api/v1/admin/ips (db.SubmitIPs) already
does, and the dashboard's own SubmitIPs client method already backs both
the top add/recheck form and the single-row recheck button.

The page also now auto-refreshes every 5s (handleIPsFragment + GET
/ips/fragment), mirroring the overview page's existing hx-trigger="every
Ns" polling and reusing the same config-driven interval
(Cfg.OverviewPollIntervalS) rather than adding a duplicate knob. Since the
table now polls itself, each row's selection checkbox gets a stable id
plus hx-preserve so a checked box survives the refresh (its own DOM node
is kept) while the rest of the row still updates live.
