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.
