Support for alternative gts.<type>.<instance_id> pattern notation

[Artifizer]

The system must support an alternative notation for identifiers in the following format.

Current notation

Schema:

{
   ...
  "properties": {
    "id": {
      "description": "UUID identifier of the event instance",
      "type": "string",
      "format": "uuid"
    },
    "type": {
      "description": "GTS type identifier for ...",
      "type": "string",
      "x-gts-ref": "..."
    },
    "occurredAt": {
      "description": "Event timestamp in RFC3339 format",
      "type": "string",
      "format": "date-time"
    }
  }
}

{
  "id": "7a1d2f34-5678-49ab-9012-abcdef123456",
  "type": "gts.x.core.events.type.v1~x.commerce.orders.order_placed.v1.0~",
  "occurredAt": "2025-09-20T18:35:00Z"
}```

**Alternative notation**

Some services (via GET or POST endpoints) must also support the combined identifier format:
`gts.<segment1>~<segment2>~<UUID>`

Using this format, the example above becomes:

Instance:

{
"id": "gts.x.core.events.type.v1x.commerce.orders.order_placed.v1.07a1d2f34-5678-49ab-9012-abcdef123456",
"occurredAt": "2025-09-20T18:35:00Z"
}```

schema:

{
  ...
  "properties": {
    "id": {
      "description": "GTS instance identifier including the type and instance UUID",
      "type": "string",
      "x-gts-ref": "..."
    },
    "occurredAt": {
      "description": "Event timestamp in RFC3339 format",
      "type": "string",
      "format": "date-time"
    }
  }
}
