Fix Slow Run Retrieval

Issue: #846

Python Version(s) Tested: 3.13

Operating System(s): Ubuntu 25.04

📝 Summary

The retrieval of Run objects is very slow for large quantities.

🔍 Diagnosis

• The pagination seems to be working.
• The default of get_runs has alerts=False but alerts is a property of the Run LLAPI class. The base class __repr__ method iterates through all properties meaning because the "alerts" key was missing the automatic 'get from server' method was being called for each run.

🔄 Changes

• I have removed this automatic retrieval, hopefully it does not break things.
• Added local_default value to be used when object is in "local" mode.
• "Local" mode used for get - bulk item retrieval.
• Object will not print elements it does not have retrieved, if the user attempts Run(...).alerts when they used get_runs(alerts=False) a KeyError will be returned.

✔️ Checklist

• Unit and integration tests passing.
• Pre-commit hooks passing.
• Quality checks passing.
