Previously the loop broke after processing the first zone file it found.
If dev.zone already existed (created by apply_ip_range), it would be
processed and the loop would stop — leaving any other zone files (e.g.
cell.zone from an earlier domain) in place. get_dns_records() reads all
.zone files so the stale zone appeared doubled in the UI.
Fix: collect all non-local zone files first, write the target, then
delete every file that is not the current domain's zone.
