Shipping methods hidden when delivery_note exists

[robsoned]

Description
Intelipost shipping methods are not shown when a delivery option contains a delivery_note. The module creates a carrier-level RateError before checking the delivery_risk_areas configuration, causing Magento to hide all Intelipost methods—even though the Intelipost API returns valid delivery options. This occurs regardless of whether risk-area handling is enabled or disabled.

Steps to Reproduce

1. Configure the Intelipost module normally.
2. Enter a destination postal code that triggers a delivery_note in the Intelipost API response
3. Proceed to checkout and attempt to retrieve shipping methods.

Expected Behavior

• Shipping methods that Intelipost returns as valid should appear in the checkout.
• A delivery_note should not cause the entire carrier to error out.
• Risk-area behavior should respect the delivery_risk_areas configuration:
• If disabled: skip only the affected method.
• If enabled: show the method normally, optionally log or annotate it.

Actual Behavior

• When a delivery_note is present, the module immediately creates a RateError.
• The carrier RateResult is marked as error = true before the configuration is evaluated.
• Magento filters out all Intelipost shipping methods.

Additional Context

The issue is caused by the placement of setError(true) and append($error) before the delivery_risk_areas check. Any delivery_note, even when Intelipost still returns multiple valid delivery options, triggers a full carrier failure.
