fix: resolve CI failures across all workflows

aitbc-agent-sdk (package-tests.yml):
- Add AITBCAgent convenience class matching test expectations
- Fix test_agent_sdk.py: was importing nonexistent AITBCAgent, now tests
  the real API (Agent.create, AgentCapabilities, to_dict) plus AITBCAgent
- Fix 3 remaining mypy errors: supported_models Optional coercion (line 64),
  missing return types on _submit_to_marketplace/_update_marketplace_offer
- Run black on all 5 src files — zero mypy errors, zero black warnings
- All 6 tests pass

python-tests.yml:
- Add pynacl to pip install (aitbc-crypto and aitbc-sdk import nacl)
- Add pynacl>=1.5.0 to root requirements.txt

Service readiness (api-endpoint-tests.yml, integration-tests.yml):
- Replace curl -sf with curl http_code check — -sf fails on 404 responses
  but port 8006 (blockchain RPC) returns 404 on / while being healthy
- Blockchain RPC uses REST /rpc/* endpoints, not JSON-RPC POST to /
  Fix test_api_endpoints.py to test /health, /rpc/head, /rpc/info, /rpc/supply
- Remove dead test_rpc() function, add blockchain RPC to perf tests
- All 4 services now pass: coordinator, exchange, wallet, blockchain_rpc
- Integration-tests: check is-active before systemctl start to avoid
  spurious warnings for already-running services

Hardhat compile (smart-contract-tests.yml, package-tests.yml):
- Relax engines field from >=24.14.0 to >=18.0.0 (CI has v24.13.0)
- Remove 2>/dev/null from hardhat compile/test so errors are visible
- Remove 2>/dev/null from npm run build/test in package-tests JS section
