Agentic: Fix Registration Issues (5564)

[danieldudzic]

Description

This PR addresses the following issues:

1. Registration was failing with VALIDATION_ERROR: Missing required fields: wooSydeCommerceId
2. Unregistration would delete the token even when it failed, causing state inconsistency
3. Auto-registration was creating an endless retry loop - if registration failed for any reason, the system would attempt to register on every page load, spamming PayPal's endpoint and logs with failing requests
4. No logging made it impossible to debug failures

Future Considerations

• If we want auto-registration, we should consider adding more robust retry logic
• Or add a setting to disable auto-registration for debugging purposes
