feat(fifa17): card-definition identity catalog + owned-item wire-id policy

fut::catalog — Fifa17CardCatalog maps a semantic CardDefinitionId to a FIFA 17
render identity (resource_id = (version<<24)|asset_id; version 0 => resource==
asset). Versioned JSON (schema_version=1, game=fifa17); validates schema/game,
rejects asset_id > 24 bits, and rejects two card ids claiming one resource_id.
Unknown definitions resolve to None (callers drop, never fabricate).
Fifa17WireItemIdPolicy carries the owned-item namespace (base 100_000_000,
first id 100_000_001, per the oracle) supplied to the generic store.

Adds serde derive to the adapter. 8 catalog tests; 3/3 mutations killed
(resourceId-drops-version, conflict-detection-off, asset-range-off).
Phase commit 2/5. No card->asset DATA shipped: the synthetic Core catalogue is
unmappable (see seed plan); the loader + format land now, population later.
