Fixed Address in mailbox given does not comply with RFC 2822, 3.6.2. [sc-202022]

[inietov]

Description

When the user accepts/declines an asset if the setting alert_email is set, and that value is formed of multiple emails comma separated, the system fails.

To fix this issue I convert that string value into an array of strings (emails) on the CheckoutAcceptance model function that return those addresses.

Fixes shortcut sc-20202 and rollbar 16977

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Test Configuration:

• PHP version: 8.2
• MySQL version: 8.0.31
• Webserver version: PHP Dev Server
• OS version: Debian 11

[what-the-diff]

• The routeNotificationForMail() method was changed to return an array of recipients instead of a single recipient.
• This change is necessary because the alert_email setting can now contain multiple email addresses separated by commas, and we need to send notifications for each address in that list.
