Server-authoritative economy: wire client to server; entry + rewards on hub

Server:
- daily (/api/daily, /api/daily/claim) + shop (/api/shop/buy) + ChargeEntry
- GameRoom (via IServiceScopeFactory) deducts ranked entry at match start and
  applies match rewards at match-over, broadcasting profile + reward over the hub
- tested: daily, shop (owned-guard), ranked entry deduction pushed over hub

Client:
- SignalrService routes profile/coins/plan/daily/shop/match to the server (Bearer);
  onProfile/onReward hub events; guest/offline fall back to local
- session-store syncs profile from hub; game-store serverReward; GameScreen shows
  live ranked reward from hub (no double submit), submits client-run games
- single source of truth in live mode (no economy divergence)

Postgres-ready via config (Provider=postgres); EnsureCreated for now.
