Track the catalog zone SOA serial per view instead of a single global value.
The new CatalogZone model has a 1:1 FK to netbox_dns.models.View and its own
soa_serial field; each view's catalog zone now increments independently. The
existing global serial is preserved during migration by copying it into every
view's new CatalogZone row.
Change CatalogZoneMemberIdentifier.name from globally unique to unique per
catalog zone (UniqueConstraint(name, catalog_zone)) and add a catalog_zone FK
to enforce it.
Remove the dns-settings management command, which was a generic interface over
the now-removed IntegerKeyValueSetting model.
Increment both catalog zone serials when a zone moves between views: the old
view's catalog zone loses a member and the new view's gains one, so both must
be bumped. Also refresh the member identifier's catalog_zone FK on a view move
so it does not go stale. The pre_save handler now captures _old_view_id and the
post_save handler detects view changes, increments the old view's serial inside
on_commit (before the new view's), and re-creates the identifier.

Per PR review feedback:
- Rename settings: custom_field_force_notify -> notify_ns_custom_field_name,
force_notify_port -> notify_ns_port.
- Add notify_ns_all_zones (bool, default False) to enable the feature globally
for every zone; it coexists with the per-zone custom field — a NOTIFY is sent
if the global switch is on OR the zone's custom field is set.
- Rename the internal job/scheduler/log strings to the notify_ns naming for
consistency (SendZoneNSNotify, schedule_notify_ns).
- Update README and CHANGELOG.
- Introduced `custom_field_force_notify` setting to trigger immediate NOTIFY to a zone's nameservers when its SOA serial number changes and the custom field is set to True.
- Updated README to document the new feature and its configuration.
- Refactored notify handler to include a new job for sending forced NOTIFY messages directly to zone nameservers.
- Enhanced zone signal handling to check for SOA serial changes and trigger forced NOTIFY accordingly.

Range of bug fixes and improvements
modified: netbox_dns_bridge/signals/netbox_dns_zones.py
1. On zone deletion the catalog zone serial was not incremented, causing clients
not to delete the zone until another zone is created/modified. Fixed using
post_delete signal.
2. Even with the notify_clients feature disabled, the client IPs were still
being tracked. This disables the unnecessary behavior.
3. _track_seen_client function in DNSBaseRequestHandler did not have the 'self'
reference parameter, causing calls to fail. Fixed.

Disable NOTIFY feature by default and add setting to enable it.
