"""API-level tests for `GET /api/tips/{workspace_id}` and its dismiss route.

Guards two things a unit test on the service can't see:
  - the wire shape (`TipResponse`) actually carries `anchor_date`/
    `anchor_range` and `message_key` + `data` — not rendered prose;
  - the dismiss endpoint round-trips through the real DB and a second GET
    no longer returns the dismissed tip.
