Floor `get_rando_addr` port at 1024, not 1000 

Ports below 1024 are privileged on linux
(`net.ipv4.ip_unprivileged_port_start = 1024`), so a non-root
`.bind()` on one raises `PermissionError`. The old `1000 +` floor
could roll into the 1000-1023 range and trip flaky `[Errno 13]
Permission denied` registry-listener binds; bump the base to 1024
so every generated port is non-privileged.
