refactor(payments): one canonical catalog order for storefront, offer, admin; admin active/all toggle

The wallet storefront listed products in creation order — its purchases and its
chip-exchange values were unsorted, unlike the admin console and the public offer.
Extract the ordering (chip packs first by rouble price, then chip-priced values
grouped hints → no-ads → combo → tournament and by chip price) into one comparator,
compareCatalogRank over a small rank key, and apply it at all three sites
(projectCatalog, projectOfferPricing, SortAdminCatalog) — so the subgroup ranking
(valueGroup) and the full order now live in one place. The rewarded "watch for
chips" CTA is a wallet-driven element rendered above the packs, so it is unaffected
and stays on top.

Also add the admin catalog active/all toggle: AdminCatalog takes includeInactive,
the console shows active products by default and ?all=1 lists archived ones too
(the detail and grant forms keep loading all products).

Tests: a storefront canonical-order unit test (reproduced the unsorted bug first);
an integration test for the active/all toggle. Existing offer/admin order tests
unchanged — behaviour preserved.
