Fix Jenkins-update flow: redeploy_project pull + delete_image safety + delete_container

Bug fixes from product test:
1. redeploy_project: BUILD_FAILED now includes explicit image pull (stop → pull → start)
2. delete_image: Distinguishes running vs stopped containers, suggests system_prune for stopped refs
3. New tool delete_container: Verify stopped state before deletion, confirmation required

Tests added for all three paths plus stopped-container edge cases.
