test: Add Python security vulnerabilities test case

[satya-blend360]

This test verifies:

• 🔴 CRITICAL: Hardcoded credentials, SQL injection, command injection
• 🟠 HIGH: Missing error handling, unsafe eval()
• 🟡 MEDIUM: Poor error handling, no type hints, division by zero
• 🟢 LOW: Debug mode in production, PEP 8 violations
• ✅ GOOD: Well-written function with type hints and parameterized queries

Will test:

• Python tech stack detection
• Flask framework detection
• Severity level tagging for Python-specific issues
• PEP 8 style guide enforcement

🔴 Critical Issues

• test-python-api.py:6 - Hardcoded credentials (DATABASE_URL, SECRET_KEY, API_TOKEN) pose a significant security risk. Use environment variables instead.
• test-python-api.py:12 - SQL injection vulnerability in get_user function due to direct string interpolation in SQL query. Use parameterized queries to prevent this.

🟠 High Priority

• test-python-api.py:23 - Missing error handling in fetch_data function. Wrap the API call in a try/catch block to handle potential failures gracefully.
• test-python-api.py:28 - Command injection vulnerability in backup_data function due to lack of input validation on filename. Validate and sanitize user input before using it in system commands.

🟡 Medium Issues

• test-python-api.py:34 - Using eval() in calculate function is dangerous and can lead to code injection. Replace it with a safer alternative for evaluating expressions.
• test-python-api.py:41 - No zero division check in divide function. Add a check to prevent division by zero and handle the error appropriately.
• test-python-api.py:51 - Missing type hints and docstrings for process_payment function. Add type hints for parameters and return type, along with a docstring explaining the function's purpose.
• test-python-api.py:63 - Function names should follow PEP 8 conventions. Rename CalculateTotal to calculate_total and Total to total.

🟢 Low Priority

• test-python-api.py:66 - Debug mode enabled in production (app.run(debug=True)). This should be set to False in production environments to avoid exposing sensitive information.

✅ Good Practices

• test-python-api.py:70 - Well-written get_user_by_id function with proper error handling and use of parameterized queries to prevent SQL injection.
