test(fifa17): real host<->Core economy integration harness

Spawn Core (axum) on an ephemeral loopback port backed by a disposable temp-file
SQLite, seed a fifa17 profile via the real Core HTTP API, then drive the HOST's
REAL transport (HttpCoreClient: CoreEconomy) + handlers against it — no fakes:
credits reads Core balance; match-reward writer credits via Core grant_reward;
purchasegroup full-gen renders the owned pack from a Core entitlement (no
sentinel); userMassInfo overlay derives coins from the same Core state
(credits==massinfo==Core invariant). Restart phase reboots Core from the same
on-disk DB and proves coins + entitlements persist. Temp dir + 127.0.0.1:0 only;
no prod DB/ports/containers/.105. dev-deps: openfut-core, tokio, axum.
