feat: integrate P2P trading into Telegram mini app

- Add 8 Supabase edge functions for P2P operations (get-internal-balance, get-payment-methods, get-p2p-offers, accept-p2p-offer, get-p2p-trades, trade-action, p2p-messages, p2p-dispute) - Add frontend P2P API layer (src/lib/p2p-api.ts) - Add 8 P2P components (BalanceCard, OfferList, TradeModal, CreateOfferModal, TradeView, TradeChat, DisputeModal, P2P section) - Embed P2P as internal section in App.tsx instead of external link - Remove old P2PModal component - Add ~70 P2P translation keys across all 6 languages
