fix: resolve Telegram command handler errors for /status and /positions (issue #74)

Fixed AttributeError exceptions in /status and /positions commands:
- Replaced invalid risk.calculate_pnl() with inline P&L calculation from balance dict
- Changed risk.circuit_breaker_threshold to risk._cb_threshold
- Replaced balance.stocks access with account summary from output2 dict
- Updated tests to match new account summary format

All 27 telegram command tests pass. Live bot testing confirms no errors.
