Subject: [PATCH] Add EUR/USD pair constants and EurUsdStrategyConfig

- EURUSD in PAIR_INFO; new per-pair price_precision and default_spread
  fields on both pairs (backtester consumes default_spread when --spread
  is omitted)
- EurUsdStrategyConfig ported from feature/eurusd-support plus EUR-local
  cost knobs (round_trip_cost=1 pip, min_tp_cost_multiple=10,
  min_sl_pips=8) so SignalConfig's gold-dollar values never apply to EUR;
  donor-tuned values are a pre-realism baseline pending re-tune
- PlatformConfig.eur_strategy field; track EUR in news currencies
