[FIX] payment_authorize: Show UserError to user

Steps:
- Install website_sale and payment_authorize
- Set up a tunnel (e.g. ngrok)
- Log in to Authorize.Net backend
- Go to Account > Response/Receipt URLs > Add Url
- Enter the tunnel URL
- In Odoo, go to Website > Configuration > eCommerce > Payment Acquirers
- Edit "Authorize.Net"
  - Credentials tab:
    - State: Test Mode
    - API Login Id, Transaction and Signature key
    - Save, then Generate Client Key
  - Configuration tab:
    - Payment Flow: Payment from Odoo
- Stop the server
- Replace https://github.com/odoo/odoo/blob/1b9b99dc2643910c1412b564affccf02ba1e55d9/addons/payment_authorize/models/authorize_request.py#L46 with `resp = {'messages': {'resultCode': 'Error', 'message': [{'code': 'E00027', 'text': 'An error occurred during processing. Call Merchant Service Provider.'}]}}`
- Restart the server
- Go to "Website" > "Go to Website" > Shop
- Add a product to the basket
- Check out the basket
- Choose "Credit Card (powered by Authorize) Test Mode"
- Pay Now
- Enter any card data (e.g. 4111 1111 1111 1111 - 01/22 - 900)

Bug:
When the Pay Now process is done, the customer is redirected to
`/shop?error=invalid_token_id`. No errors are shown.

Explanation:
The patch simulates an error from Authorize.Net happening during their
process. Using the special card numbers won't trigger the wanted
behavior.

When getting an error from Authorize.net, a `UserError` is raised. This
error is then caught in the controller to return a formatted message.
However, returning a dict in this part of the code embeds it inside
`{'result': [...]}`. The error message is, thus, not blocking the form's
redirection and the user gets redirected to the form action, i.e.
`/shop/payment/token`. This route requires `pm_id`, but, in this
scenario, it's an empty string. This leads to another redirection to
`/shop/?error=invalid_token_id` as seen here:
https://github.com/odoo/odoo/blob/1b9b99dc2643910c1412b564affccf02ba1e55d9/addons/website_sale/controllers/main.py#L938-L941



Letting the error bubble up forces the backend to return a blocking
error response. This makes the fronted display the Authorize.Net error
underneath the provider selection, and prevents it from redirecting.
