Fix port allocation to ignore stopped instances

Browse Source 
Port allocator was counting stopped QEMU instances as occupying ports,
preventing new starts after stop-all. Only running instances now block
port reuse. Stopped instances with flash images on disk are preserved
for esp_qemu_flash; truly stale entries are purged.
