Update SSH access patterns documentation and expand workflow integration test suite

- ssh-access-patterns.md: Clarify ns3/aitbc container setup with correct paths and service names
  - Add container hostname verification command
  - Update paths: /etc/aitbc/blockchain.env, /opt/aitbc/apps/blockchain-node/
  - Fix service name: aitbc-blockchain-node (not aitbc-blockchain-node-3)
  - Add service restart and log viewing examples
- test_workflow.sh: Rewrite as comprehensive integration test suite
  - Add

scripts/testing/test_config_profiles.sh
