WHY IT NEEDS A POLICY

Why payware_authorization_oauth2_token_helper needs a policy

The tool creates or manages OAuth2 tokens, which is a Write operation (creating credentials/session tokens). It is not purely Read since it can create new tokens. While tokens could be misused for financial transactions, the tool itself is an authentication/authorization helper, not a payment operation. Severity is medium because a misused or leaked token could enable unauthorized API access.

From the tool's definition 'Create or manage tokens' and 'Create new OAuth2 tokens (if none exists)'
