/**
 * Module-local error codes for admin-users.
 *
 * Follows the same `code + factory` shape used by `AuthError` in
 * `@byline/auth`, but with its own class so consumers can distinguish
 * admin-users-specific failures from generic auth failures (e.g. to
 * translate `EMAIL_IN_USE` into a 409 at a transport boundary while
 * `FORBIDDEN` maps to 403).
 *
 * The codes are intentionally prefixed — `admin.users.*` — so they sort
 * alongside the matching ability keys in logs and admin UI messages.
