fix: code references count returns 0 after unchanged rescan

[Zaimwa9]

Thanks for submitting a PR! Please check the boxes below:

• I have read the Contributing Guide.
• I have added information to docs/ if required so people know about the feature.
• I have filled in the "Changes" section below.
• I have filled in the "How did you test this code" section below.

Changes

• ignore_conflicts=True was skipping creating a new code reference record when scanning an unchanged code reference
• We use a filter based on the last scanning created_at=F("repository__last_scanned_at") so while last_scanned_at advanced, there was no related code_reference on this date
• Switched to update_conflicts=True with unique_fields and update_fields being created_at and revision (only ones updated on conflict)

Impact appeared starting from second scanning.

How did you test this code?

• Updated test to also check the payload is properly returned after conflicting update

Code Review

This pull request updates the code reference recording logic in record_scan to update conflicts on duplicate records instead of ignoring them. Specifically, it configures update_conflicts=True with unique fields ["feature", "repository", "code_references_hash"] and updates ["created_at", "revision"]. Additionally, the unit tests have been updated to verify that code references remain retrievable after handling duplicate payloads. I have no feedback to provide as there are no review comments.
