Incorrect Zod schema generation for OpenAPI 3.1 prefixItems/tuple structures

[aaazzam]

When generating Zod validation schemas from OpenAPI specifications that use prefixItems to define tuple structures (common when working with Python APIs that use Tuple types), Orval generates invalid TypeScript with syntax errors including:

• Duplicate zodzod namespace references
• Incorrectly placed commas and syntax in tuple definitions
• Malformed Zod validation code that fails to compile
