FI-3358: Check for Duplicate Ids in In-Memory Repositories

[vanessuniq]

Summary

This PR addresses a performance issue in the JSON API caused by collisions of entity or runnable IDs. Duplicate IDs lead Inferno to reindex tests every time a test is fetched from the repository, significantly impacting performance. To prevent this, the PR introduces a check that detects duplicate IDs before entities are inserted into the repository. If duplicates are found, Inferno will fail to start, prompting the user to resolve the ID collisions.

Testing Guidance

• Tested with the G10, which contains duplicate test IDs in the US Core Test Kit.
• Confirmed that Inferno fails to start due to the detected duplicates
