Refactor AIConfig to Sanitize Input for Goal Parameters (#3492)

* Update remove_color_codes to handle non-string input

The `remove_color_codes` function now accepts any type of input that can be cast to a string. Previously, it was only accepting string input and not casting non-string types to string which was causing errors in some cases.

The changes were made to both logs.py and its corresponding test file.

* Refactor AIConfig to Sanitize Input for Goal Parameters

Details:
- Modified `ai_config.py` to correctly handle and sanitize user input for AI goals and convert them to formatted strings, to fix an issue where some specially formatted ai_settings.yaml files were causing goals to load as list[dict]
- `test_ai_config.py` includes a test for the `sanitize_input` function in `AIConfig` class.
- Removed unnecessary tests from `test_logs.py`

* Update for readabiity

* Update for readabiity

* Updates for conciceness

* Updated tests to confirm AIConfig saves goals as strings

* FIxed trailing space at end of line
