feat(proxy-groups, current-proxy-card): auto-refresh delay sorting

- proxy-groups: recalculate active group head and reapply delay sort after tests so list reorders automatically when "按延迟排序" is active.
- current-proxy-card: add delaySortRefresh trigger after auto/manual latency checks to immediately refresh selector and proxy list ordering.
- current-proxy-card: listen for delaySortRefresh to keep displayed delay chips and option ordering aligned with latest measurements.
