🧹 Code health: Refactor ResourceRecyclerModule_PersistsAndEjectsBufferedAndPendingOutput

[marko1olo]

🎯 What: Split the giant ResourceRecyclerModule_PersistsAndEjectsBufferedAndPendingOutput method in ModAssetBindingLifecycleEditTests.cs into 9 smaller, focused test methods, and fixed documentation code health issues detected by the validation sweeps.
💡 Why: A massive test method is difficult to maintain and read. Splitting it by logical domain (e.g., CultivationManager, BaseModule, SaveData, DeepDrillModule) significantly improves maintainability without altering the tests' functionality. Additionally, fixed the doc structural issues to maintain code health.
✅ Verification: Verified by running the test suite via the full verification sweep (RunFullVerifySweep.py). All tests passed successfully, and the tests were confirmed split locally via git diff.
✨ Result: The codebase is cleaner and tests are now well-segregated by domain, resulting in better test discoverability and readability. Doc structure checks also pass correctly.
