Fringg ae99358ae9 fix: pricing audit — display/charge parity, race conditions, balance locks ...

M-2: tariff_purchase.py — _apply_promo_discount delegates to PricingEngine,
     _get_user_period_discount returns (group_pct, offer_pct, combined),
     all ~15 call sites updated for display/charge price parity

M-4: miniapp switch_tariff — add FOR UPDATE lock on subscription,
     commit=False for atomic balance+transaction, emit_transaction_side_effects

M-6: CryptoBot — defer status commit (commit=False) so webhook retry works
     if fulfillment fails

WARNING: add lock_user_for_update before balance_kopeks mutations in
     contest_attempt_service, wheel_service, admin/referrals,
     account_merge_service, cabinet/routes/contests
