Refactor initialize-spider-db.py for improved readability

[coderabbitai]

Context

As discussed in PR #1606 (comment: #1606 (comment)), the initialize-spider-db.py script would benefit from refactoring to improve readability by splitting the main function into smaller, focused helper functions.

Suggested Improvements

The main() function in components/clp-py-utils/clp_py_utils/initialize-spider-db.py should be refactored into logical helper functions such as:

• Loading and validating CLP configuration
• Validating database credentials
• Setting up the Spider database and tables

Additional Considerations

Similar logic repetition exists in multiple places across the codebase. Consider addressing these patterns together in a comprehensive refactoring effort.
