Migrate Model Loading from File System to MLflow with Redis Integration

[taxe10]

Description

Update Arroyo SAS to load models from MLflow instead of the file system, and modify the Redis instance to track which models to retrieve from MLflow.

Requirements

• Refactor model loading mechanism to fetch models from MLflow registry
• Update Redis instance to know which MLflow model URI and version should be used
• Implement fallback mechanism if MLflow retrieval fails
• Update documentation for new model retrieval workflow and unit tests

Reference

• Current implementation loading the ML model: https://github.com/als-computing/arroyoSAS/blob/main/src/arroyogisaxs/lse/lse_reducer.py#L167
