Problem

When creating or updating dashboards from a PersesDashboard CRD (either via apply or dashboards create), user-settable annotations (dash0.com/folder-path, dash0.com/sharing, dash0.com/source) are silently dropped.

The ConvertToDashboard() function in internal/asset/persesdashboard.go copies dash0.com/id from labels into dash0Extensions.id, but does not copy any annotations from the Perses CRD metadata into the typed DashboardAnnotations struct.

This only affects the PersesDashboard code path — regular kind: Dashboard definitions work correctly because their typed Annotations struct is deserialized directly.

Expected behavior

Annotations set on a PersesDashboard CRD should be carried through to the API request, just as they are for regular Dashboard definitions.

Steps to reproduce

1. Create a PersesDashboard YAML with a dash0.com/folder-path annotation:

   apiVersion: perses.dev/v1alpha1
   kind: PersesDashboard
   metadata:
     name: my-dashboard
     annotations:
       dash0.com/folder-path: /my/folder
   spec:
     display:
       name: My Dashboard

2. Run dash0 apply -f dashboard.yaml or dash0 dashboards create -f dashboard.yaml
3. Retrieve the dashboard — the folder-path annotation is missing
