Harden ontology handling for Zep-backed simulations

[nativ3ai]

Summary

• normalize generated edge names to Zep-compatible SCREAMING_SNAKE_CASE before ontology submission
• skip malformed ontology rows and invalid attribute/source-target entries instead of crashing on missing keys
• allow the Vite dev server port to be overridden via MIROFISH_FRONTEND_PORT

Why

Running MiroFish against Grok-generated ontologies exposed two failure modes in the graph pipeline:

1. mixed-case edge names such as ANALYzes are rejected by Zep
2. malformed entity or edge rows from the ontology LLM output can trigger KeyError: 'name'

These changes make the pipeline tolerate that noise and keep the simulation workflow moving.

Validation

• python3 -m py_compile backend/app/services/graph_builder.py backend/app/services/ontology_generator.py
• verified the patched flow locally against Grok + Zep on real simulation runs
