[Obs AI Assistant] Add ebt telemetry

[neptunian]

Summary

Adds 3 ebt events:

• tool calls observability_ai_assistant_tool_call
• deleting conversations observability_ai_assistant_conversation_delete
• duplicating conversations observability_ai_assistant_conversation_duplicate

Testing

1. To test in dev mode, in your kibana yaml file set:
   telemetry.localShipper: true

2. Create the actions that trigger the events (call a tool, delete and duplicate a conversation)

3. Query the server events in the telemetry index filtering by the event name:

GET ebt-kibana-server/_search
{
  "size": 1,
  "query": {
    "bool": {
      "filter": [
        {
          "term": {
            "event_type": "observability_ai_assistant_tool_call"
          }
        }
      ]
    }
  }
}
