Automatic Base64 Encoding for Webhook Basic Authentication

NetBrain's webhook follow-up action currently requires users to manually base64 encode their username and password before entering the combined string into the Authorization header when configuring Basic Authentication. This manual step introduces the risk of formatting errors and requires customers to perform the encoding outside of NetBrain using external tools. This enhancement would allow NetBrain to accept a plain username and password for Basic Authentication and automatically perform the base64 encoding internally before constructing the Authorization header. Customers with security requirements around credential handling would benefit from a more streamlined and less error-prone configuration process when setting up webhook integrations.
