feat(desktop/account-health): mark freshly bound accounts as live

Bind callbacks now stamp the runtime account as health=live with a fresh
verified_at and seed the health record via markTrackedAccountBound, so the
UI doesn't show a just-bound account as 尚未校验 while waiting for the next
probe. Also let force probes bypass the cached-result short-circuit so the
manual 重新校验 button always re-runs the probe.
