/**
 * Practitioner search covers the specialty column, against real Postgres.
 *
 * The property lives in SQL: the route's `where` OR filters name, practice
 * AND specialty case-insensitively. A mocked client cannot go red on it —
 * the filter it is meant to prove runs in the database, not in the handler.
 * So this seeds a row whose ONLY hit for "Zahn" is its specialty and asserts
 * the route returns it, plus a control row that must not come back.
