// Give `notices` the `created` field everything already sorts by.
//
// The collection was declared with exactly the fields it needs -- message,
// active, endsAt -- and PocketBase does not add `created`/`updated` unless they
// are asked for. Both readers ask for `sort=-created`:
//
//   - the app's NoticeService, which caught the resulting 400 and swallowed it,
//     so a notice never appeared and nothing said why;
//   - the status dashboard's own listing, which therefore always showed "zatím
//     žádné" no matter how many notices existed.
//
// So the feature had never once worked end to end, and the failure was
// invisible from both ends. Writing worked; nothing could read what was written.
//
// `onCreate` only for `created`; `updated` moves on every save, which is what a
// pull cursor wants and costs nothing here.
