ci: update all workflows to use standardized AITBC directory structure

- Ensure standard directories exist in all CI workflows:
  - /var/lib/aitbc/data - Blockchain database files
  - /var/lib/aitbc/keystore - Wallet credentials
  - /etc/aitbc/ - Configuration files
  - /var/log/aitbc/ - Service logs

- Updated workflows:
  - python-tests.yml
  - integration-tests.yml
  - api-endpoint-tests.yml
  - security-scanning.yml
  - systemd-sync.yml
  - docs-validation.yml
  - package-tests.yml
  - smart-contract-tests.yml
  - js-sdk-tests.yml
  - rust-zk-tests.yml
  - cli-level1-tests.yml

This aligns CI/CD with the multi-node blockchain deployment workflow
and ensures consistent directory structure across all environments.
