Code Review
The pull request introduces a security validation step for Python code executed in Pyodide within the CSVAgent. This is a crucial improvement to prevent potential remote code execution vulnerabilities by rejecting unsafe constructs in LLM-generated or custom Python code. Additionally, a minor change was made to httpSecurity.ts to accept all status codes for secureAxiosRequest when handling redirects, which is a reasonable adjustment for robust redirect handling.

This new validation step is a critical security enhancement. By validating customReadCSVFunc before execution, you effectively prevent malicious or unsafe Python code from being run in the Pyodide environment, mitigating potential remote code execution (RCE) risks. This directly addresses the objective of limiting code to avoid potential issues.

This is a follow up to #5701 (Adding the validation here was missed).
CSVAgent runs LLM generated code using Pyodide. We want to limit the code that is run to avoid potential issues. Changes include:
