feat(V2): migrazione alpaca completa
Task 6.7: porting alpaca da services/mcp-alpaca a src/cerbero_mcp. client.py + leverage_cap.py copiati 1:1 (default cap 1 cash). tools.py: 17 tool senza ACL/Principal/audit. Router /mcp-alpaca con 18 route (env_info + 17 tool). Builder branch alpaca: paper=(env=="testnet"), api_key viene da settings.alpaca.api_key_id. Test client + leverage_cap migrati (15 test alpaca pass). Test builder con stub SDK alpaca-py. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
