/**
 * Administratively editable fields per eden.md §1.1.2 — and *only* those.
 * `pfCpf`, `pjCnpj`, and `pjRepCpf` are deliberately not declared here:
 * with the global ValidationPipe's `forbidNonWhitelisted` (main.ts), any
 * request that tries to send them is rejected outright rather than
 * silently ignored. Changing the document itself would need a dedicated
 * re-verification flow — never a side effect of a generic admin PATCH.
 *
 * `registrationStatus` is validated as one of the 5 legal *values* here;
 * full state-machine transition legality (e.g. blocking `rascunho`→`ativo`
 * directly) is NOT enforced in this MVP — matches the legacy, which also
 * has no dedicated transition endpoint (eden.md §1.1.1: "não há endpoint
 * dedicado de transição", just this same generic PATCH).
