auto no prefix needed

[xzrderek]

Note

Introduces automatic normalization of Fireworks model identifiers to ensure compatibility with LiteLLM and downstream components.

• Adds normalize_fireworks_model in evaluation_test_utils and applies it in evaluation_test to both global completion_params and per-invocation kwargs
• Updates tests to pass unprefixed Fireworks models (e.g., accounts/.../models/...); Pydantic agent factory strips the prefix when constructing the provider-specific model; remote server test continues to assert prefixed model in row.input_metadata.completion_params
• Minor cleanup: remove unused imports, simplify use_priority_scheduler condition, small formatting tweaks
