CLEANUP: Remove static generated_models.py file

The BOOST Python implementation uses dynamic schema-driven model generation,
not static model files. Pydantic models should be generated at runtime from
JSON schemas to maintain the dynamic, schema-driven architecture.

This aligns with the design principles documented in README.md:
- Dynamic Schema-Driven Architecture
- Pydantic models generated directly from JSON schemas
- Automatically adapts to schema changes without code modifications

The generate_missing_models.py script was helpful for analysis but the static
output file contradicts the dynamic design approach.
