/**
 * DomainException (Base)
 *
 * Base class for all translatable domain exceptions.
 * Exceptions carry an i18n key + optional args so the application-layer
 * exception filter can translate them into the caller's locale at the HTTP
 * response boundary.
 *
 * Subclasses should:
 *   - Pass an i18nKey (e.g. 'error.PORT_NOT_FOUND')
 *   - Pass i18nArgs for interpolation (e.g. { portCode })
 *   - Optionally override `status` (HTTP status, default 400)
