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.

Router /mcp-deribit/* monta 34 tool (28 read + 6 write) come endpoint
POST /mcp-deribit/tools/{tool_name}, con DI per env (request.state) e
client (ClientRegistry). Write tools costruiscono creds minimale
{max_leverage, client_id} da settings per leverage cap enforcement.
Test deribit migrati: test_client.py + test_leverage_cap.py riassegnati
sotto tests/unit/exchanges/deribit/ con import rewrite mcp_* -> cerbero_mcp.*.
Skip dei legacy V1-only test_environment_info / test_server_acl / test_env_validation
(ACL e resolve_environment eliminati in V2).

Copiati e aggiornati i test da services/common/tests/ a tests/unit/common/.
Import aggiornati da mcp_common a cerbero_mcp.common. Eliminati test di
funzionalità V1-only (app_factory, environment, auth/Principal, server_base).
Refactored test_audit.py (principal→actor str) e test_mcp_bridge.py
(TokenStore→valid_tokens set). 71/71 test passano.
