feat(check-ip): add --serve HTTP mode to exercise dataset.Tick
Long-running server exposes GET / (client IP) and GET /check?ip= for
ad-hoc lookups. signal.NotifyContext drives graceful shutdown; the
shared dataset.Group.Tick goroutine refreshes inbound/outbound views
in the background so the refresh path gets real exercise.

Factored the shared populate+report logic into a Checker struct so
oneshot and serve modes use the same code path.
