Optimize and Validate DNSTwist Scan

[jayjaybunce]

🗣 Description

1. Updated Blocklist API to accept bulk ips
2. Updated "update_blocklist" scan to perform bulk inserts/updates and query blocklist.de concurrently to decrease runtime
3. Updated DNSTwist to reduce runtime and improve data accuracy, using the updated /blocklist/check endpoint and performing concurrent operations when available and using bulk update/create operations when possible
4. Fixed issue with DNSTwist sync that was returning 422 status code for org sync pushes.

The move to bulk checking is a great feature, but the current implementation introduces a significant performance risk for our database.

Performance (Blocker): The code performs Blocklist.objects.get(ip=ip) inside the for loop. This creates an N+1 query problem. Please refactor this to use Blocklist.objects.filter(ip__in=ip_addresses) to retrieve all data in a single database query.

Security: Please add a check to limit the length of ip_addresses (e.g., max 100) to prevent resource exhaustion attacks on the Lambda.

Typos: Please fix "Determing" -> "Determining" in the docstring.
