What does this PR do?

This PR adds support for Direct Preference Optimization (DPO) training
via the existing HuggingFace inline provider. It introduces a new DPO
training recipe, config schema updates, dataset integration, and
end-to-end testing to support preference-based fine-tuning with TRL.

Test Plan

Added integration test:

tests/integration/post_training/test_post_training.py::TestPostTraining::test_preference_optimize

Ran tests on both CPU and CUDA environments
