"""End-to-end contract and connectivity tests for the dashboard wrapper.

These intentionally cover only the happy-path lifecycle against a real backend —
that the SDK can create, read, mutate, find, and delete a dashboard, and that the
config blob round-trips through the backend with the schema the frontend expects.
Exhaustive validation/serialization cases live in the unit tests.
