/**
 * Regression tests for the feedback-settings write path (#1030).
 *
 * The admin event form posts its whole client-side feedback state back,
 * including three keys that were never columns on event_feedback_settings:
 * `enable_rate_limiting`, `rate_limit_window_minutes` and
 * `rate_limit_max_requests`. Spreading those into the knex UPDATE threw,
 * the route answered 500, and EventDetailsPage swallowed it — so the admin
 * saw "Event updated successfully" while "Enable feedback" never persisted
 * and guests could not leave any feedback.
 *
 * Pinned here:
 *  - UI-only keys are dropped, not written, on BOTH the insert (no row yet)
 *    and update (row exists) branches.
 *  - Every real column still round-trips.
 *  - Identity columns can't be mass-assigned through the settings body.
 *  - gallery.js no longer declares a duplicate GET /:slug/feedback-settings.
 *    server.js mounts galleryRoutes before galleryFeedback, so the duplicate
 *    shadowed the real handler and dropped the #655 per-guest caps from the
 *    guest payload.
