Move durable workflow samples to 04-hosting/DurableWorkflows

Aligns with main branch sample reorganization where durable samples
live under 04-hosting/ (alongside DurableAgents/).

- Move samples/Durable/Workflow/ -> samples/04-hosting/DurableWorkflows/
- Add Directory.Build.props matching DurableAgents pattern
- Update slnx project paths
- Update integration test sample paths
- Update README cd paths and cross-references
