fix(vlm): load code formula processor from repo id

[lorenzozanee]

Fixes #2568

Formula enrichment was loading the processor from the cache path, which can misresolve tokenizer and config data for the CodeFormulaV2 VLM path.

Keep the processor on the repo id while leaving weights and generation config on the resolved cache path.

Tests:

• uv run pytest tests/test_transformers_engine_processor_source.py -q

@lorenzozanee Your suggested fix breaks the contract that an artifact_path is always provided when docling must run offline. It also does not address #2568 at all. The behaviour seen there is not an artifact of wrong preprocessing, it is native extraction / image-export behavior when the code-formula model does not run.

Hence I will close this PR.
