Link a signal card

Attach a generated signal card to a stored score, or claim an anonymous signal card for the caller’s account after sign-up. Symmetric with /api/score/link but for the IC-tier signal card flow.

curl -X POST https://app.dacard.ai/api/signal-card/sigc_xyz/link \
  -H "Authorization: Bearer $DACARD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "scoreId": "scr_xyz" }'
