Process WooCommerce orders for DHL shipping label creation

# Setup
## Generally
- The environment variable `NODE_FUNCTION_ALLOW_BUILTIN` has to equal or include the value `crypto` (FYI: is default on n8n cloud) as it is required to run this workflow


## To test the workflow
1. Set a valid email address of a user that exists in WooCommerce in the Mock Node "Mock Data"
2. Enable the node "Mock Data"
3. Disable the node "Decrypt email address"
4. Use the built-in chat by pressing the "Chat" button


## For production use:
1. Update the "System Message" in the node "AI Agent" for specific use case. At least the name of the shop should be changed
2. Integrate the chat into the website. An example can be found in the box "Example Website Implementation"
3. Disable or delete the node "Mock Data"
4. Enable the node "Decrypt email address"
5. Enable Workflow
