feedback7 R22-HUD: the card 梓兰's 猎头顾问 freezes shows its frost — every shop card draws its own slot's freeze, not the toggle's (GitHub #354 by @DuolaCCCCat); golden: unchanged

Seen (reproduced on the parent, notes repro-354.mjs): band_orchid's active refresh copies the top-tier operator into another
slot and freezes the copy (bands/meta.js band_shop_refresh_copy_max_lv_char, slot.frozen = true) while shop.frozen — the
toggle — stays false; m.private sends both (views.js: shop.frozen and slots[i].frozen). The shop bar passed the toggle
(`frozen = !!shop.frozen`) to every ChessCard / ItemCard, so no card showed the frost: the server kept the card to the next
prep, the player could not see which one.

Now: shopBar.js slotFrozen(slot, toggle) = the slot's own flag, or the toggle (a frame without per-slot flags — the dev
mock — and the old behaviour for the 冻结 button, which still copies the toggle onto every unsold slot); both card kinds
use it. The bar's frame (is-frozen) and the 冻结 / 解冻 button stay on the toggle. The rule is not touched (bands.test.js,
and the new test): a second manual refresh re-rolls the frozen card too — like the toggle, "再手动刷新会重抽" — and
freezes one of the new pair; with no further refresh the frozen card stays in the next prep (the flags are cleared
then, round.js startRound).

- Tests: test/ui/feedback7-orchid-freeze.test.js (4: the wire — exactly one frozen card of the pair, toggle off — and the
  cards drawn from it; the toggle still freezes every slot; the rule unchanged across two refreshes and a round; the
  ShopBar source pin); fails on the parent (no slotFrozen, the cards passed `frozen`).
