Cloudflare 5xx pages from Deribit testnet were leaking through the JSON
parser as JSONDecodeError → UNHANDLED_EXCEPTION. Wrap response parsing so
upstream errors surface as a retryable HTTP_502 envelope instead.

Su errore di Deribit (auth fallita, ecc.) i campi equity/balance/margin/
available/unrealized_pnl/total_pnl ora sono None: signal chiaro di "valore
ignoto" vs "saldo realmente a zero". Risolve ambiguità lato client che
leggevano equity=0 senza accorgersi del campo error.

Quando Deribit risponde con {"error": {...}} su public/auth (creds errate,
scope mancante, env mismatch), il client esplodeva con KeyError: 'result' →
500 UNHANDLED_EXCEPTION sui tool privati (get_account_summary, get_positions).
Ora _authenticate solleva DeribitAuthError tipizzata, _request la converte
in error envelope coerente con il resto del flusso.

- ruff: contextlib.suppress al posto di try/except/pass (client_registry, test_env_routing)
- rimozione services/ legacy (residuo da git rm)
- fix integration test fixture: rimosso sys.modules.pop che inquinava module references nei test successivi (test_audit, test_client_init_default_http)
254 test passano. Ruff: clean. Mypy: 68 warning preesistenti dal codice V1 migrato (strict=false).

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).
