Aaron Guise 83fbb03cad fix: relativize zone-apex hostnames to '@' for CoreDNS MySQL 🐛
CoreDNS MySQL (cybercinch fork) expects '@' for zone-apex references in
record RDATA. Storing the full FQDN (e.g. 'ithome.net.nz.') caused CoreDNS
to strip the zone suffix and serve 'MX 0 .' / 'CNAME .' instead of the
correct apex target.

- Add _relativize_name(): converts zone FQDN → '@', in-zone subdomains →
  relative label, external FQDNs left unchanged. Handles both already-
  relativized output from dnspython ($ORIGIN present) and absolute FQDNs
  when $ORIGIN is absent from the zone file.
- Replace _normalize_cname_data() with _relativize_name(); add
  _normalize_mx_data(), _normalize_ns_data(), _normalize_srv_data() using
  the same helper.
- _parse_zone_to_record_set() now normalizes MX, NS, SRV alongside CNAME.
- _ensure_zone_exists() sets managed_by='directadmin' on create and
  back-fills NULL rows from pre-migration installs.
- Zone.managed_by changed to nullable=True to match ALTER TABLE migration
  where existing rows have no value.
- schema/coredns_mysql.sql updated to reflect actual two-table schema with
  managed_by column and migration comment.
- 11 new tests (130 total, all passing).
