/**
 * Re-kinds a rule when the user switches tabs in the editor, keeping whatever
 * the target kind can still use.
 *
 * Preserving `id` is what makes an edit an edit: the sheet matches the draft
 * back to the original by id, so a regenerated one would append a duplicate
 * rule instead of updating the one being edited.
 *
 * `columns` is what makes "can still use" more than a guess: the Farbverlauf tab
 * offers only number and date columns, so carrying a text column across would
 * leave its dropdown blank while the rule still pointed at that column — and an
 * applied gradient on an unorderable column silently never paints.
