### Resource Provider

Microsoft.Network/firstPartyServiceTags

### Description of Feature or Work Requested

Add Azure CLI support for managing First Party Service Tag resources and associating them with supported public IP configurations.

The requested work includes:

1. Add commands to create, update, retrieve, list, delete, and wait on  Microsoft.Network/firstPartyServiceTags  resources.
2. Support referencing a First Party Service Tag from Public IP Address and Public IP Prefix IP-tag configurations.
3. Support the  firstPartyServiceTagId  property in VM and VMSS implicit public IP configurations.
4. Support asynchronous create, update, and delete operations through  --no-wait  and a corresponding  wait  command where applicable.

The command group should preferably be generated using AAZ and initially marked Preview.

There is a known Swagger schema discrepancy for  resourceGuid. The 2025-09-01 service response returns  resourceGuid  at the root of the First Party Service Tag resource, while the published specification currently defines it under properties.

The PowerShell implementation applies an AutoRest transform that moves  resourceGuid  from  FirstPartyServiceTagPropertiesFormat  to the root  FirstPartyServiceTag  model. The CLI implementation may require an equivalent AAZ customization.
