modified: pyproject.toml

Fix paths after restructuring

renamed:    netbox_dns_bridge/management/commands/export-dns-zone.py -> netbox_dns_bridge/management/commands/dns-export-zone.py
renamed:    netbox_dns_bridge/management/commands/export-all-dns-zones.py -> netbox_dns_bridge/management/commands/dns-export-zones.py
Unify command naming scheme

new file:   netbox_dns_bridge/migrations/0001_initial.py
Adds the missing migration. Since the plugin was renamed this is also an opportunity to merge all changes into a single migration.

renamed:    netbox_dns_bridge/service/transfer/catalog_zone_manager.py -> netbox_dns_bridge/catalog_zone_manager.py
renamed:    netbox_dns_bridge/service/transfer/dns_server.py -> netbox_dns_bridge/dns_server.py
new file:   netbox_dns_bridge/management/commands/dns-settings.py
modified:   netbox_dns_bridge/management/commands/dns-transfer-endpoint.py
renamed:    netbox_dns_bridge/service/transfer/request_handler.py -> netbox_dns_bridge/request_handler.py
deleted:    netbox_dns_bridge/service/transfer/__init__.py
Another restructure to simplify code re-use. New command dns-settings added to allow setting of catalog zone serial.
This will be needed to migrate from previous versions.
