"""Regression: GET /api/fundraising/state heals blank grid-pill emails from the relational mirror.

The grid blob is canonical for the mobile "Edit investor" sheet, but an email can reach a linked
classic contact (email capture / a contact edit) without ever being written back into the blob pill
— so the edit form showed an empty email for a contact the directory clearly had (Grant, 2026-06-20).
The state handler now fills a blank pill email from fundraising_contacts.email, else the linked
contacts.email, matched by pill order then name. This asserts:
  - a blank pill whose linked contact has an email is HEALED on read;
  - a blank pill whose linked contact is also blank stays blank;
  - a pill that already carries an email in the blob is NEVER overwritten (fill-only).
Synthetic data only.

Run: cd backend && python3 test_grid_email_heal.py
