fix(spec): define network zone asns/locations as arrays instead of allOf wrappers

Fix ValidationError in list_network_zones() for Dynamic and Enhanced Dynamic zones

Summary

Fixes a Pydantic ValidationError raised by NetworkZoneApi.list_network_zones() and get_network_zone() when a response contains a DYNAMIC or DYNAMIC_V2 zone with asns or locations values. This includes the empty list [] the API returns for Enhanced Dynamic zones with no ASNs configured.

Problem

pydantic_core.ValidationError: 1 validation error for EnhancedDynamicNetworkZoneAllOfAsnsInclude
  Input should be a valid dictionary or instance of EnhancedDynamicNetworkZoneAllOfAsnsInclude
  [type=model_type, input_value=[], input_type=list]

Because a single bad zone fails deserialization, the whole paginated list call fails.

Root cause

openapi/api.yaml declared these fields by wrapping an array schema in allOf:

include:
  allOf:
    - $ref: '#/components/schemas/NetworkZoneAsns'   # type: array
    - description: An array of ASNs to include ...

OpenAPI Generator 7.7.0 treats this wrapper as a new object type, so it generated empty models with no fields instead of List[...]. Pydantic correctly rejects a list for an object type. This isn't caused by Pydantic v2 strictness or by empty lists: populated lists fail too, and the empty models would drop the data anyway.

The pattern appeared in 6 places:

Model	Field	Before	After
DynamicNetworkZone	asns	DynamicNetworkZoneAllOfAsns	List[StrictStr]
DynamicNetworkZone	locations	DynamicNetworkZoneAllOfLocations	List[NetworkZoneLocation]
EnhancedDynamicNetworkZoneAllOfAsns	include / exclude	...AsnsInclude / ...AsnsExclude	List[StrictStr]
EnhancedDynamicNetworkZoneAllOfLocations	include / exclude	...LocationsInclude / ...LocationsExclude	List[NetworkZoneLocation]

IP zones (gateways / proxies) are not affected.

Changes

• openapi/api.yaml: replaced the 6 allOf wrappers with inline array definitions. Descriptions are kept, and maximum: 75 / nullable: true are copied from the referenced components.
• Regenerated: dynamic_network_zone.py, enhanced_dynamic_network_zone_all_of_asns.py, enhanced_dynamic_network_zone_all_of_locations.py, their docs, and the lazy import maps in okta/__init__.py and okta/models/__init__.py.
• Removed: the 6 obsolete wrapper models, their docs, and their links in okta/DOC_GUIDE.md.
• Tests: added tests/test_network_zone_arrays.py.

Breaking change note

The 6 wrapper classes are removed (DynamicNetworkZoneAllOfAsns, DynamicNetworkZoneAllOfLocations, EnhancedDynamicNetworkZoneAllOf{Asns,Locations}{Include,Exclude}).
They had no fields and could never hold data, so no working code could have depended on them. The on-wire JSON shape is unchanged.

Testing

• tests/test_network_zone_arrays.py: 48 tests covering empty, populated, and null payloads, discrimination through NetworkZone.from_dict, to_dict / JSON round trips, _links, proxyType validation, and regression guards for the removed models.
• 39 of the 48 tests fail against the pre-fix models, confirming they catch the bug.
• Coverage of the 4 changed models is 97%. The 5 uncovered lines are generator else branches for dict-valued nested fields, which can't be reached with Pydantic v2 validation on.
• Existing unit tests and the network zone integration tests pass.
