security: add safe.ReadAllLimited — bound all HTTP response body reads to 10MB

- Created safe/io.go with ReadAllLimited helper (default 10MB limit)
- Replaced 62 unbounded io.ReadAll(resp.Body) calls across 32 files
- Covers all exchange traders (Hyperliquid, Bybit, Binance, OKX, Aster,
  KuCoin, Gate, Bitget, Lighter, Indodax), providers (CoinAnk, Alpaca,
  TwelveData), MCP client/x402, market data, wallet, telegram, kernel
- Prevents OOM from malicious/buggy exchange API responses
- Previously fixed: brain.go, sentinel.go already had manual LimitReader

### Code Quality
- [DONE] Extract WelcomeScreen, ChatMessages, ChatInput from AgentChatPage (825→480 lines)
- [DONE] Sanitize 3 more error message leaks in API responses (handler_trader.go ×2, handler_ai_cost.go ×1)
- [PENDING] `context.Background()` used in ~69 exchange/trader calls — should propagate request context for proper cancellation (partially done: kline handlers fixed, trader/exchange calls remain)
