WHY IT NEEDS A POLICY

Why payware_authentication_test_jwt needs a policy

This tool executes a JWT creation process including cryptographic operations (SHA-256 hashing) and token generation. While it appears to be a testing/diagnostic tool, it actively runs a multi-step process involving serialization and hash calculation rather than simply reading data. It does not move money or destroy data, but it executes authentication credential generation logic.

From the tool's definition 'Test JWT token creation process with detailed step-by-step breakdown, showing deterministic JSON serialization, SHA-256 hash calculation, and final JWT structure'
