Fix: get /apps/:id/bricks must return the same response as /apps/:id/bricks/:id

[dido18]

Motivation

The Applab expcts that the GET /v1/apps/:id/bricks and GET v1/apps/:id/bricks/:id return the same JSON response.

Current

arduino@dido:/$ curl 127.0.0.1:8800/v1/apps/ZXhhbXBsZXM6cmVhbC10aW1lLWFjY2VsZXJvbWV0ZXI/bricks | jq
{
  "bricks": [
    {
      "id": "arduino:web_ui",
      "name": "WebUI - HTML",
      "author": "Arduino",
      "category": "ui",
      "status": "installed",
      "require_model": false
    },
    {
      "id": "arduino:motion_detection",
      "name": "Motion detection",
      "author": "Arduino",
      "category": "",
      "status": "installed",
      "require_model": true
    }
  ]
}

Change description

Use the same struct for both endpoints.

New response
