test: add edge case tests for URL detection in OpenAICompatibleEmbedder

- Add tests for URLs with 'embeddings' in non-endpoint contexts
- Add tests for URLs with 'deployments' in non-endpoint contexts
- Verify actual endpoint URLs are still correctly identified
- Addresses PR review feedback for better test coverage
