// Persist a watch-state toggle from any Plex surface: flip via the caller's `optimistic` cache
// updater, call the API, surface a failure (the click used to look dead on 403/404/429), then
// `resync` (invalidate) — which corrects the optimistic flip to truth either way. Shared by the
// browse grid and the person page, each of which owns a different cache shape.
//
// `revert` is called on a failure only, to put the card back where `resync` does not, or not at once:
// a component's local copy of the rows (a Plex playlist), which an identical refetch never re-seeds
// (react-query keeps the same `data`), or a cache whose refetch lands later than the click's answer.
