Refactor error handling and update tests

Browse Source 
Refactored error handling in OllamaChatEndpointCaller by extracting status code checks into a helper method. Improved logging for image loading errors in OllamaChatRequestBuilder. Updated integration and unit tests to relax assertions and clarify comments. Minor documentation formatting fixes and Makefile improvement for reproducible npm installs.
