feat(fifa17): attach economy services in Server::from_config

Wire the PRODUCTION constructor so the economy authority is not test-only.
Server::from_config now builds one process-lifetime AsyncBridge, opens the
durable MarketStore + PileStore (paths from config), shares one HttpCoreClient
as both CoreAccess and CoreEconomy, builds the content pool from Core, and
attaches EconomyServices via with_economy. Stores/bridge are host-lifetime, never
per request.

- config.rs: required OPENFUT_MARKET_DB / OPENFUT_PILE_DB (durable file paths;
  must survive host restart — no temp defaults).
- Fail-closed startup: a bridge/store that cannot initialize returns Err from
  from_config (host refuses to start) — NEVER a silent omission or a Python
  economy fallback.

Test: from_config_constructs_and_serves_economy — builds the Server via the REAL
from_config (disposable config: temp market/pile/identity + a catalog file
derived from seeded content + the real tables dir) against a live Core, drives
credits / purchasegroup / Store BUY / market list-query-buy through it, then
rebuilds from the SAME config after a Core restart and asserts the balance
persisted. host 71 lib + 3 integration + 24 host_test green; clippy/fmt clean.
