/**
 * An estimate as the admin API publishes it.
 *
 * Carries the stored columns, the dates already rendered in the company's date
 * format, the shareable PDF link, and the notes with their placeholders
 * interpolated rather than the raw template stored on the row.
 *
 * The related records -- lines, contact, author, document taxes, custom field
 * values, company and currency -- are each gated behind an existence probe on
 * the relation, so a missing one leaves its key out of the payload entirely.
 * Every probe is its own query, which is deliberate here: the estimate payload
 * has to answer correctly whether or not the caller eager-loaded anything.
