Get Dashboard By Id

Get a specific dashboard from the local database.

Accepts either a Metabase integer dashboard ID or a Superset embed UUID (dual-run, AI-7926) — the frontend routes Superset spaces by UUID.

Identity contract per provider: for Metabase rows the returned id is the Metabase dashboard id and can be used to refetch here; for Superset rows embed_uuid is the identity (used for routing and refetching) and id is only an opaque row identifier.

Returns: MetabaseDashboardDetail with dashboard information
