[bid-manager-api] feat: Add query cache and report reuse

[Vasist10]

This PR implements caching logic for the Bid Manager API to avoid generating duplicate reports when the same query is issued multiple times. The feature stores and reuses query_id and report_id associated with a query_hash, reducing API calls and improving performance.

issue: #208

Added unit tests covering both pathways:

• test_get_response_reuses_cached_report()
• test_get_response_creates_and_caches_report()

@Vasist10, thank you so much for the contribution and working on the issue #208!
Everything's looks good to me.
Do you want me to bump the version on pypi for easier installation or having code on github is sufficient?

I just noticed it has already been deployed to PyPI.
Thank you for bumping the version! Really happy to see the caching improvement included in the release
