//   - Endpoint registration for all OpenCue interfaces
//   - gRPC handler registration process
//   - HTTP method handling
//   - Content-type validation
//
// Running Tests:
//   - Docker (recommended): ./run_tests.sh (select option 1)
//   - Local Go: go test -v .
//   - With coverage: go test -cover -v .

// This test validates that the JWT middleware correctly:
//   - Accepts requests with valid, non-expired JWT tokens
//   - Rejects requests without Authorization headers
//   - Rejects requests with malformed or invalid tokens
//   - Rejects requests with expired tokens
//
// Security is critical here - any failure in these tests indicates a
// potential authentication bypass vulnerability.
//
// Test Cases:
//   - Valid Token: Should return 200 OK
//   - Missing Token: Should return 401 Unauthorized
//   - Invalid Token: Should return 401 Unauthorized
//   - Expired Token: Should return 401 Unauthorized
