Problem

The <asset> list -o yaml and <asset> list -o json commands output the raw API list-item summaries (id, dataset, name, origin) instead of the full asset definitions.
This makes the output unsuitable for backup, version control, or re-applying with dash0 apply -f -.

For example, dash0 dashboards list -o yaml used to produce:

- dataset: default
  id: a1b2c3d4-...
  name: My Dashboard

This is not a valid dashboard definition and cannot be used with dash0 apply.

Expected behavior

• <asset> list -o yaml outputs full asset definitions as a multi-document YAML stream (separated by ---), directly pipeable to dash0 apply -f -.
• <asset> list -o json outputs an array of full asset definitions.
• The output should be equivalent to calling <asset> get <id> -o yaml for each asset individually.
• This applies to all four asset types: dashboards, check-rules, views, and synthetic-checks.
