Prevent resuming a saved preset

[ZenAlexa]

Closes #4204.

What changed

I stop dstack preset resume once preset.yml has been committed. The saved preset also owns its list row, and its creation session supplies progress details.

PresetStore.save() atomically publishes the artifact before run cleanup. The resume check now follows that durable completion point.

Verification

• Preset service and CLI tests on e54083b7: 353 passed, 2 skipped.
• Ruff, Python compilation, and diff checks passed.

I've synced this with current master and updated the regression fixtures for session_id.

The saved preset continues to own completion and its list row; the expanded preset tests cover that behavior on the updated branch.
