Ensure accurate Job Description (JD) scraping from Job page

[Mayank-glitch-cpu]

The Job Description (JD) currently scraped from the Job page sometimes contains gibberish or unrelated text. Please ensure that:

• The JD is extracted precisely and exclusively from the visible designated section on the job page.
• No unrelated or garbled text is included in the JD field.
• If site structure or selectors have changed, update the scraping logic to target only the intended textual content.
• Add tests, if possible, to detect and avoid text extraction errors in the future.

This will improve data quality for downstream features and analytics.
