Notify LLM on endpoint create/update

[matKlju]

AS A Service-Module admin
I WANT the LLM module to be notified when an API endpoint is created or updated
SO THAT the LLM api-tool index stays up to date

---

Description

When an endpoint is created or edited from either API Registry or Service Flow, the Service Module must notify the LLM module.

LLM endpoint:

POST http://ruuter-internal:8086/rag-search/api-tools/index

Payload per endpoint:

{
  "endpointId": "<endpoint.endpointId>",
  "name": "<endpoint.name>",
  "description": "<endpoint.description>",
  "url": "<selected definition url/openApiUrl/path>",
  "method": "<selected definition methodType>",
  "params": [
    {
      "name": "...",
      "type": "...",
      "required": true,
      "description": "..."
    }
  ]
}

Acceptance Criteria

• LLM module is notified on endpoint create
• LLM module is notified on endpoint update
• Trigger works from API Registry
• Trigger works from Service Flow
• Payload includes: endpointId, name, description, url, method, params
• URL is resolved from selected endpoint definition
• Endpoints without resolvable URL are skipped silently
• LLM notification failure does not block save flow
• Notification errors are logged
