Download error fix - CensusCountyBusinessPatterns

[kartik-s21]

The main.py script for CensusCountyBusinessPatterns was failing during the data download phase.The script calculates the default "data_end_year" as two years prior to the current year (in 2026, it defaults to 2026-2=2024), but the source has not yet published the 2024 dataset. This caused the script to crash with Error 404: File Not Found.

So what Is done -
Modified scripts/census_county_business_patterns/main.py to make the download process more resilient:

• Wrapped a Try-Except Block over the dowload.
• Instead of crashing, the script now logs a warning and continues to the next available file or year.

Code Review

This pull request improves the reliability and security of data ingestion scripts by adding exception handling for network requests, implementing path traversal checks during zip extraction, and filtering for specific file extensions. It also includes minor code cleanups in the energy dataset scripts and test files. Feedback suggests addressing an indentation issue, removing an unused variable, and extending error handling to include corrupted zip files.
