List feeds and sheets

{ feeds: [{ id, kind (rss | sheet), url, title, platforms, template, mode, post_at, interval_minutes, max_items, timezone, status_col, enabled, last_checked_at, last_status, last_error, failures, items_posted, next_check_at }], plan: { name, limit, used, every_minutes, every, items_per_read, rows_per_read, ai, ai_drafts_a_day, scheduled_queue, min_interval_minutes, approvals, sheets } }. A sheet's last_error can be a note while last_status is ok: rows with problems, rows changed after they were scheduled, rows left for the next read.
