Get a PIX key claim
Reads one claim live from DICT (§8.2.15 Consultar Reivindicação). Nothing local is consulted: account_id exists only to validate the caller and to produce the ISPB §8.2.15 requires, and the plugin’s own key row is deliberately ignored because it is absent for a claim this plugin never opened and gone once the row is soft-deleted.
So this route serves the same universe as the default GET /v1/claims: any claim DICT associates with the caller’s ISPB, including one opened by another account of the same institution. Note what the response does NOT carry - only claimId, key and ispb are serialized. DICT’s situation and which side of the claim you are on are read and then dropped, so this route cannot tell you whether a claim is open, confirmed or cancelled; read state from GET /v1/claims?status=processing or GET /v1/entries instead. A claimId DICT does not know is 404 PIX-0020, and DICT being unavailable is 503 PIX-1050.
