feat(e2e): add run-on-host.sh for automated cron on railiance01

CUST-WP-0028-T06:
- e2e/run-on-host.sh: standalone script for native execution on railiance01
  (no SSH from workstation). git pull → compose up → health wait →
  test_full_flow.py → compose down → report to state-hub via ops-bridge.

Install via: make e2e-cron-install REPO=activity-core  (from ~/the-custodian)
